World No. 1 tennis player Jannik Sinner may be making headlines for his dominance on the court, but his personal life is now grabbing just as much attention. After Sinner admitted in an Italian interview that he is “in love,” fans quickly speculated that the mystery woman is none other than Danish model Laila Hasanovic.

Hasanovic, who was spotted cheering for the Italian during his US Open semifinal win over Felix Auger-Aliassime, has since become a trending name online.

Why do fans think Sinner is dating Laila Hasanovic?

Speculation about Sinner’s love life has been building for months, but a small detail after his third-round victory against Denis Shapovalov sent the rumors into overdrive.

• Sinner was caught on camera checking his phone courtside.
• Social media users claimed they recognized Laila Hasanovic’s photo as his wallpaper.
• A TikTok video of the moment went viral, with one fan posting: “Sinner has a photo of Laila Hasanovic on his lock screen so the rumors are…?”

The coincidence—combined with her presence at his US Open matches—has only fueled speculation, though neither Sinner nor Hasanovic has confirmed the relationship.

Who is Laila Hasanovic?

Born in 2000, Hasanovic is a Danish model and influencer with a growing international presence.

• She has worked with luxury brands including Prada Beauty and Armani Beauty.
• As of September 2025, she boasts 376,000 Instagram followers and nearly 49,000 YouTube subscribers.
• She was also a Miss Universe finalist, bringing her into the global spotlight.

Hasanovic has previously been linked to Formula One driver Mick Schumacher, son of F1 legend Michael Schumacher. The pair went public in 2023 but reportedly split in 2024, with both later spotted on the elite dating app Raya.

Is Jannik Sinner really dating her?

While the evidence is circumstantial, there are several reasons why fans believe the connection is real:

• Sinner’s recent interview with Italian outlet Corriere della Sera, in which he admitted he is in love.
• Hasanovic’s visible support during his US Open matches.
• Past public relationships have already placed her in the spotlight of European sports media.

Still, both Sinner and Hasanovic have avoided confirming or denying the rumors, leaving fans to speculate.

Jannik Sinner on his private life

The 23-year-old tennis star has long been private about his relationships. In his pre–US Open interview, when asked if he was in love, he simply responded:

“Yes, but we don’t talk about our private life.”

That remark was enough to set fans searching for clues, with Hasanovic fitting the profile of someone who could match Sinner’s rising fame and global lifestyle.

Why this matters for fans

Romantic speculation often swirls around top athletes, but Sinner’s case has struck a chord because of his rapidly growing global profile. With Novak Djokovic nearing the twilight of his career and Carlos Alcaraz rising alongside him, Sinner has emerged as a future-defining player. Fans now seem equally invested in who he’s sharing his victories with off the court.

If the rumors are true, Hasanovic’s presence in Sinner’s box could become a familiar sight at tournaments worldwide, adding a layer of glamour to his already headline-making career.

TL;DR

Tennis star Jannik Sinner has admitted he is “in love,” sparking speculation that he is dating Danish model Laila Hasanovic. Fans point to his rumored phone wallpaper and her appearances at the US Open as evidence, though neither has confirmed the relationship. Hasanovic, a Miss Universe finalist and fashion model with a growing following, was previously linked to Mick Schumacher.
