Laila Hasanovic wasn’t in the stands when the majority of tennis fans first learned about her. She was looking at a phone screen. Vigilant spectators saw a picture of a young woman on Jannik Sinner’s phone’s lock screen during the 2025 US Open. The identification was made in a matter of hours as the picture swiftly went viral on social media. It was the kind of unintentional revelation that would have been hard to stage and impossible to undo. Sinner remained silent about it. He didn’t have to.
There was no doubt left by the time he won the Vienna Open in October 2025. Speaking in English during his victory speech, Sinner thanked his family, team, and girlfriend—publicly revealing their relationship for the first time. That night, Hasanovic was there in the crowd. In just one tournament cycle, the couple had gone from being the subject of tennis internet rumors to receiving official recognition.
It is important to note that Laila Hasanovic is Danish, as some early accounts misidentified her as Dutch. With about 524,000 Instagram followers, she is in a noteworthy but modest position as an influencer. In addition to creating content and modeling, she launched NRD55, a self-tanning brand, adding an entrepreneurial element to her public persona that sets her apart from celebrities whose notoriety is solely related to social media. Before she established her own platform, she had a more formal introduction into the modeling industry as a Miss Denmark finalist.
Prior to Sinner, she had dated Mick Schumacher, the son of seven-time Formula 1 world winner Michael Schumacher, who had a brief Formula 1 career. Although the circumstances of the two partnerships are obviously different, the pairing with Sinner puts her back in the orbit of elite world sport. Men’s tennis and Formula One follow different schedules and are subject to different forms of public pressure.
Sinner’s desire to keep his private life hidden has remained constant. He stated in a 2024 interview with Vanity Fair Italia that he intends to maintain things that way and that he would rather talk about tennis than his personal life. Hasanovic and the couple don’t post about one another, and neither has discussed the relationship in interviews, suggesting that they are on the same wavelength. Visibility in competitions, which is its own kind of communication, is what they have in common.
Cameras kept going back to Hasanovic in the stands as Sinner won his second Wimbledon championship in July 2026. She received considerable criticism on the internet for her composed manner during games—restrained in situations where the partners of other players would be clearly nervous. The response was different when Sinner prevailed, and video of that moment went viral. When someone is being studied so intently, it’s the kind of detail that becomes apparent.
