The tennis world’s attention wasn’t just on Jannik Sinner’s powerful forehand during his US Open semifinal clash. Danish model Laila Hasanovic sat courtside at Arthur Ashe Stadium, her presence adding another layer of intrigue to speculation that has followed the World No. 1 throughout the 2025 season. What started as whispered rumors has now become the kind of story that has fans analyzing every camera angle and social media post.
What Sparked the Latest Round of Speculation About Jannik Sinner’s Love Life?
Sinner has long kept his personal life private, but his high profile in the tennis world naturally invites curiosity. The speculation began building momentum earlier in 2025 when Sinner was seen with Russian model Lara Lieto in Monte Carlo, triggering relationship rumors he publicly denied.
However, the Hasanovic connection gained more credibility through a series of carefully documented sightings. Later in the season, observers spotted Sinner in Copenhagen with a female companion, further stirring speculation about the Danish model. The Italian star has previously maintained that his trips to Denmark were strictly professional, tied to photoshoots rather than personal engagements.
The rumors gained serious traction when Sinner himself hinted at being “in love” during the 2025 US Open but refused to name the person involved. That admission set the tennis community buzzing, but what happened next turned speculation into a social media frenzy.
The buzz intensified dramatically when cameras focused on Sinner’s phone following his third-round victory over Denis Shapovalov. His lock screen wallpaper closely resembled Hasanovic’s July Armani Beauty campaign, a detail that eagle-eyed fans immediately caught and shared across social platforms.
Adding more context to the story, Italian weekly Dipiù quoted Nicoletta Stampfl, co-owner of Santo Gelato in Monte Carlo, who said that Sinner and Hasanovic had spent time together at her shop. This seemingly innocent detail provided another piece of the puzzle that tennis fans were eagerly assembling.

The recent sightings have added significant fuel to the ongoing speculation. Hasanovic has reportedly been seen at several of Sinner’s biggest matches throughout 2025, including appearances at Roland Garros and Wimbledon. Her presence at the US Open semifinal against 25th seed Felix Auger-Aliassime represented the most visible confirmation yet of her interest in following Sinner’s career.
A photo of Hasanovic at the US Open semifinal surfaced on X, capturing her watching Sinner’s match from the stands, and immediately went viral among tennis fans.

The September 5 semifinal photo provided yet another visual confirmation for fans who have been tracking every detail of this developing story. Meanwhile, on the court, Sinner has delivered the kind of tennis that justified his World No. 1 ranking, defeating Vit Kopriva, Alexei Popyrin, Denis Shapovalov, Alexander Bublik, and Lorenzo Musetti to reach the semifinals.
As of the latest update, the semifinal clash between Sinner and Auger-Aliassime stood at 6-1, 3-6, 6-3, 3-2, with both players fighting for a spot in the championship match. The winner will face 2022 champion Carlos Alcaraz in Sunday’s final on September 7, setting up what promises to be an epic showdown regardless of the romantic subplot playing out in the stands.
