Deniz Can Aktaş’s Girlfriend in 2026: Who Is He Dating Now?

Introduction

To sum it up, things are complicated, and not in a good way. Deniz Can Aktaş started 2026 with a girlfriend most fans did not know much about. Now, he might end the year with a new partner, a cheating scandal in the middle, and no official statement to clear things up.

If you are here because you searched his name and “girlfriend” together, you have probably already seen fragments of this story in a TikTok clip, a gossip tweet, or a headline that raised more questions than it answered. This piece puts it all in one place, in order, with the parts that are confirmed clearly separated from those that are still just rumors.

Who was Deniz Can Aktaş’s ex-girlfriend?

Before any rumors about Devrim Özkan started, Aktaş was reportedly in a relationship with Gizem Yaren Yıldırım, a physiotherapist.

Unlike a lot of his co-stars, Aktaş has never been especially public about his personal life, so most of what is known about this relationship comes from fan accounts and gossip pages rather than anything he has posted himself.

Most of the evidence of their relationship comes from older TikTok videos in which they appear together. These videos have captions like “Denizcan and Yaren’s adventures” and feel casual and low-key, which makes it seem like their relationship is genuine rather than just for publicity.

Unlike many names that get pulled into celebrity dating rumors, Yıldırım is not a public figure in her own right; she has a real, separate career independent of any connection to Aktaş.

She is a sports physiotherapist who previously worked at Acıbadem Sports, a FIFA Medical Center of Excellence facility in Istanbul.

In 2026, she opened her own clinic, where she now handles athlete rehabilitation, ACL pre- and post-surgery recovery, and chronic pain treatment.

Her Instagram is a small, low-key account — under 1,000 followers, bio simply reading “Sports Physiotherapist” — with no indication she ever leaned into the public attention the relationship brought her.

She has not posted about Aktaş, the rumors, or the alleged breakup, and has stayed out of the story entirely since it broke.

That is part of why what happened next stood out. Aktaş is not someone who often generates relationship headlines. When he suddenly did, twice in the same season, people noticed.

Deniz Can Aktaş’s Dating History

The Yıldırım relationship was not Aktaş’s first time in this conversation, and it is worth laying out the fuller picture, because a pattern shows up once you do. Nearly every relationship or rumor attached to his name traces back to a co-star.

Relationship	Status	Details
Hafsanur Sancaktutan	Confirmed past relationship	His co-star on Aşk Ağlatır (Star TV). Their on-set friendship reportedly became a real relationship, and it’s the pairing Turkish outlets consistently describe as his most-discussed romance — covered independently by multiple outlets over more than a year. The relationship ended for reasons neither side has explained publicly.
Miray Daner	Rumored, never confirmed	His co-star on Hudutsuz Sevda. Fans “shipped” the pairing heavily based on their on-screen chemistry, and entertainment coverage floated it as a possible real-life relationship — but unlike the Sancaktutan relationship, this one was never confirmed by anyone involved and is generally treated as speculation rather than fact.

Devrim Özkan	Current rumor	Covered in detail below.

The through-line is hard to miss: Aktaş’s confirmed and rumored relationships have almost all started with a co-star. Sancaktutan, Daner, and now Özkan were all people he was actively filming with when the relationship rumors began.

That is a genuinely common pattern in Turkish television. Long shooting schedules and constant physical proximity make on-set relationships more likely, not less, but it also means every new co-star he is paired with on screen tends to generate the same “are they together” question almost automatically, whether or not anything is actually happening.

One more detail worth noting for context: after Sancaktutan and Aktaş split, she went on to date actor Kubilay Aka, who at the time was also linked to Miray Daner, the same actress rumored to have dated Aktaş.

Person	Connection
Deniz Can Aktaş	Dated Hafsanur Sancaktutan starting around 2019
Hafsanur Sancaktutan	After Aktaş went on to date actor Kubilay Aka (public since August 2024, breakup rumors since February 2026)
Kubilay Aka	Before Sancaktutan, he was with actress Miray Daner (2017–2019)
Miray Daner	The same actress was later rumored — never confirmed — to be linked to Aktaş during Hudutsuz Sevda

In short, Aktaş’s ex is now with someone whose own ex is the woman later rumored to be involved with Aktaş. It is a small industry, and these four names keep circling back to each other in gossip coverage worth knowing as background, even though it does not tell you anything definite about Aktaş’s current situation.

Turkish entertainment writers have pointed out the overlap themselves, half-jokingly describing the four of them as caught in a small, recurring circle of Thursday-night TV rivals whose personal lives kept crossing over.

It is a good illustration of just how small and interconnected the Turkish drama industry’s dating rumor mill really is, as the same handful of names keep resurfacing in each other’s company.

Deniz Can Aktaş’s Relationship Timeline: Exact Periods, Where Known

Some of the dates listed here are not exact. Aktaş has never talked publicly about his relationship history, so most of this timeline is based on when his shows aired and when rumors or confirmations appeared. If the exact start or end of a relationship is unknown, we say so explicitly rather than making guesses.

Relationship	Approximate period	How the dates are known
Hafsanur Sancaktutan	Began around 2019, publicly confirmed by 2020–2021, ended at an unstated date before 2024	Started during Aşk Ağlatır, which aired from September to December 2019. A later magazine piece confirmed the relationship was public and “over a year” old, placing the confirmation around 2020–2021. No official breakup date was ever given by either side.
Miray Daner	Rumored roughly 2023–2024	Coincides with Hudutsuz Sevda, which was already airing its second season by September 2024. Never confirmed as a relationship, so there’s no real “start” or “end” to point to — just a window when the rumor was active.
Gizem Yaren Yıldırım	Reported relationship through roughly early to mid-2026	Referenced in social content as his girlfriend into 2026; the unfollow and breakup speculation both surfaced around April–May 2026. Exact start date not publicly known.
Devrim Özkan	Rumors have been ongoing since around June 2026	Began with the LA nightclub sighting shortly after Yeraltı‘s season finale in June 2026 and is still unfolding as of this update, with no confirmation or denial yet.

A Quick Note on Why This Story Is Everywhere Right Now

Aktaş’s rising profile is directly tied to Yeraltı, which has become one of the highest-rated dramas on Turkish television this year.

He plays Haydar Ali opposite Devrim Özkan’s Halide Ceylan, and their on-screen dynamic was popular enough that clips of their scenes were circulating widely before anyone raised the question of a real-life relationship.

That is a fairly normal pattern for Turkish television. Co-star chemistry becomes real-life speculation almost automatically once a show finds an audience, but it usually fades if nothing backs it up.

In this case, something kept backing it up, which is the only reason a private unfollow and a blurry nightclub video turned into a sustained, multi-week story instead of a one-day rumor.

The Unfollow That Started the Breakup Rumors

At some point after Yeraltı‘s season finale, fans noticed Aktaş had unfollowed Yıldırım on social media.

That is a small action, but it is the internet’s most reliable breakup signal, and Turkish entertainment accounts picked it up almost immediately. Several ran versions of the same headline, asking whether the relationship had ended.

Aktaş and Yıldırım have not made any public statements to confirm the news. Still, soon after, social media posts mentioning “Denizcan Aktaş’s girlfriend Gizem Yaren Yıldırım, they broke up” began to appear, which suggests the unfollow was probably not just a random mistake. For now, consider this a strong and ongoing rumor, not an official announcement.

The Cheating Allegation: What is Actually Being Claimed

This is the part of the story that has not yet appeared in most English-language coverage, and it is worth being precise about because it is a serious claim resting entirely on unverified sources.

According to posts from gossip accounts covering the Yeraltı cast, footage allegedly from nightclub security cameras in Los Angeles, taken during a trip Aktaş and Devrim Özkan made right after the season finale, shows the two of them in a physically close, arm-in-arm moment.

The claim, based on that footage, is that Aktaş was involved with Özkan while still in a relationship with Yıldırım, and that Özkan’s then-boyfriend, footballer Lucas Torreira, was reportedly blindsided when he saw the footage.

Some posts even claim Özkan was still wearing a ring symbolizing her relationship with Torreira on the flight to the US, which only added to the confusion around the timeline.

A few things worth flagging clearly:

• Any of the four people involved confirms none of this — not Aktaş, not Özkan, not Yıldırım, not Torreira.
• The source is a single gossip account, not a news outlet with editorial standards or named reporting.
• The claims conflict slightly with each other depending on which post you read, which is typical of a story spreading quickly without a central verified source.

So why include it at all? Because it is part of what is actually circulating and shaping the “who is he dating now” conversation, and leaving it out would make this piece less useful, not more accurate. The responsible move is to report that the claim exists, be explicit about how thin the sourcing is, and not treat it as a fact. That is what this section is doing.

How Turkish Media Handled the Story

It is worth noting how this played out across outlets, as it says something about the reliability of each layer of the story.

The unfollow and the breakup speculation around Yıldırım were independently picked up by multiple accounts, which is a reasonably good sign that something real prompted it, as several people noticed the same public action and reached similar conclusions.

The nightclub footage and the cheating allegation, by contrast, trace back to essentially one gossip account, and other outlets that mentioned it were largely reposting or summarizing the same original claim rather than independently confirming it.

Several accounts shared the Brooklyn hand-holding photos, but none of them interviewed Aktaş or Özkan for a statement.

.

This pattern, one detail confirmed by independent sources, another based on a single unverified source, and another supported by photos but no comment, is common in how celebrity gossip stories develop. That is why this piece separates each claim rather than combining them into a single story.

So, Who Is Deniz Can Aktaş Dating Now?

The name most consistently attached to him right now is Devrim Özkan, his co-star on Yeraltı.

Fans have nicknamed the pairing “DenDev,” and it has become one of the more active Turkish celebrity tags on TikTok and Instagram.

Here is the timeline that built that rumor, laid out month by month. A note on precision: these are approximate, based on when each report or sighting was first made public. Aktaş and Özkan have never laid out a timeline themselves, so a few of these dates are best estimates rather than exact.

Month	What happened	How solid is it
February 2026	First romance rumors surface, alongside reports of on-set tension over promotional photos and the “sweatshirt clue”	Early-stage speculation, not evidence
March–May 2026	Yeraltı continues airing; on-screen chemistry between Haydar Ali and Ceylan keeps fueling “is it real?” chatter, but nothing new breaks	Ongoing speculation, no new evidence
Early June 2026	Yeraltı airs its season finale	Confirmed fact, not rumor
Mid-June 2026	Aktaş reportedly unfollows his girlfriend, Gizem Yaren Yıldırım, on social media around this time	Circumstantial, but a consistent signal
Mid-June 2026	Alleged nightclub footage from Los Angeles shows Aktaş and Özkan together shortly after the finale	Single unverified source; the most serious claim in the story
Late June 2026	Aktaş and Özkan are photographed holding hands in Brooklyn, New York, with Aktaş carrying flowers	The strongest visual evidence to date
Early July 2026	Asked directly about dating Aktaş, Özkan smiles, doesn’t confirm or deny, and redirects the conversation	Reads as closer to “yes” than “no,” still not confirmation

Simply put, no one has confirmed a relationship between Aktaş and Özkan. Still, the fact that an ex-girlfriend unfollowed him, there were cheating rumors with a co-star, photos later showed him holding hands with that co-star, and she did not deny it when asked, has led most entertainment outlets to treat this as the likely story, even though nothing official has been announced.

What This Means If You Are Trying to Get the Real Answer

If you want the short, defensible version to walk away with: Deniz Can Aktaş’s most recent confirmed relationship was with physiotherapist Gizem Yaren Yıldırım, that relationship appears to have ended based on social media activity, and he is currently rumored, not confirmed, to be involved with his Yeraltı co-star Devrim Özkan.

A cheating allegation connects those two facts, but it comes from a single unverified source and should not be treated as settled.

That is a messier answer than “he is dating so-and-so,” but it is the accurate one. Anything cleaner than that right now is either guessing or getting ahead of what has actually been confirmed.

Conclusion

This story is about a relationship that appears to have ended quietly, a serious but unverified allegation, and a possible new couple that has not yet been confirmed by anyone reliable.

That is not a satisfying answer if you wanted a clean “yes, he is dating her,” but it is accurate and worth more than a guessing headline.
