While the world focused on Jannik Sinner‘s historic rise to the top of tennis, a new figure emerged in his life: girlfriend Laila Hasanovic. More than just a partner, the Danish model and content creator has become a fixture in his player box and a growing influence in the sports world, symbolizing a new kind of power couple for the modern athlete.
In the high-stakes world of professional tennis, where every point is dissected and every move is scrutinized, the personal lives of top athletes often become public property. For Jannik SinnerLaila Hasanovic, a Danish model and content creator who has quickly become a central figure in the narrative of the sport’s newest superstar.
The relationship was officially confirmed in October 2025, following Sinner’s triumphant win at the Vienna Open. In a moment that captured the attention of the tennis world, Sinner dedicated his victory speech to his “girlfriend,” a clear and deliberate debut of their romance. While he didn’t name her, Hasanovic was easily identifiable in the crowd, sitting alongside his family. This public acknowledgment was a significant step for the notoriously private Sinner, who had previously emphasized the importance of shielding his personal life from the public eye.
A Quiet Support System in a High-Pressure Sport
For an athlete like Sinner, whose mental fortitude is as much a part of his game as his powerful forehand, having a stable and supportive personal life can be a crucial asset. Sinner himself spoke to this in a February 2024 interview with Vanity Fair Italia, long before his relationship with Hasanovic began. “Of course it’s not easy, I travel a lot and during tournaments I’m very focused. But I think it’s a wonderful thing when you find the right love,” he said. “If you think about it, the best tennis players in the world all have wives and children.”
Hasanovic’s role in his life appears to be exactly that—a quiet but powerful support system. Since her relationship with Sinner went public, she has been a consistent presence in his player box at some of the sport’s biggest events. She was spotted courtside at the French Open in May 2025, the US Open that September, and most notably, joined him on the court in Italy after he clinched the prestigious Nitto ATP Finals title against Carlos Alcaraz in November 2025. These appearances signal a level of commitment and support that is invaluable to an athlete navigating the grueling tennis season.
From Runway to Player Box: The Life of Laila Hasanovic
While her relationship with a global sports star has brought her into the limelight, Laila Hasanovic is a personality in her own right. A native of Denmark, she is a successful model and content creator with a significant social media following, boasting over 400,000 Instagram followers and more than 300,000 on TikTok. Her career has seen her walk the runway for brands like The Garment and OpéraSPORT, and she has been featured in campaigns for the luxury beauty brand Armani Beauty.
In August 2025, her profile received another boost when she attended the Venice Film Festival as part of the Armani Beauty team. “A truly pinch me moment!! From first discovering @armanibeauty as a little girl through my mom’s makeup bag, to now standing on the red carpet as part of the @armanibeauty universe — this journey feels incredibly special,” she wrote in a post on Instagram. This moment highlighted her career trajectory and demonstrated her ability to navigate high-profile events with grace, a skill that has clearly translated to her role alongside Sinner.
A New Chapter After a High-Profile Past
Before her relationship with Sinner, Hasanovic was in a long-term relationship with another high-profile athlete: Formula 1 driver Mick Schumacher. The pair reportedly dated for three years before their split in April 2025. Her social media was filled with posts chronicling their travels together, from romantic getaways to public events like the Ball des Sports gala in Frankfurt, where they were photographed together in February 2024.
This past relationship provides context for how Hasanovic has adapted to the public nature of dating a world-class athlete. While she is more private with Sinner, choosing not to post about him on her social media, she has shown a comfort level in being seen with him at major sporting and cultural events. This suggests a deliberate choice to support her partner’s career while maintaining a degree of separation between their public and private lives, a balance that Sinner himself has expressed a desire to protect.
Global Adventures and the Making of a Modern Power Couple
Their relationship is not confined to the tennis court. As a couple, Sinner and Hasanovic have traveled the globe, attending a diverse range of events that reflect their shared interests. In December 2025, they were spotted enjoying dinner in Dubai and hitting the slopes in Bolzano, Italy. The following month, they were seen together at the Formula 1 Abu Dhabi Grand Prix, walking in the paddock with F1 CEO Stefano Domenicali.
This ability to seamlessly move between the worlds of tennis and fashion, and sports and entertainment, positions Sinner and Hasanovic as a new archetype for modern power couples. Their relationship is built on a foundation of mutual respect for each other’s careers, even as they support one another through the unique pressures of public life. For Sinner, who is still in the prime of his tennis career, having a partner like Hasanovic—one who understands the demands of fame and is willing to share in the journey—could be the key to unlocking even greater success on the court. For Hasanovic, her role by his side has amplified her own public profile, creating a dynamic partnership that is as much about shared ambition as it is about romance.
