Jannik Sinner's Girlfriend Laila Hasanovic Emerges as Fashion Influencer and Tennis Supporter

Jannik Sinner, the world's number one-ranked tennis player, is dating Danish model and fashion influencer Laila Hasanovic, who founded the self-tanning beauty brand NRD55. The couple first sparked dating rumors during the 2025 US Open and have since made multiple public appearances together at major tennis events. Hasanovic brings significant social media presence to the relationship, with over half a million Instagram followers and an established career in the fashion and beauty industries.

Who Is Laila Hasanovic?

Hasanovic originates from Copenhagen and has established herself as a prominent figure in fashion and beauty circles. Beyond her social media presence, she founded NRD55, a tanning and skincare brand designed to enhance natural radiance through carefully formulated products. The brand reflects her philosophy developed over more than a decade working within the fashion and beauty sectors, emphasizing simplicity and a natural approach to beauty enhancement.

Before her relationship with Sinner became public, Hasanovic had previously dated Formula 1 driver Mick Schumacher, with the pair separating in early 2025. This connection to high-profile athletes reflects her comfort navigating the world of elite sports and international attention.

The Sinner-Hasanovic Relationship

The couple's romance emerged during the 2025 US Open when observant fans noticed Hasanovic featured as Sinner's iPhone background. Sinner subsequently confirmed their relationship publicly, acknowledging her support following his Vienna Open victory that autumn. He stated at the time, "My whole team, also watching at home, thank you so much for the support," as cameras captured Hasanovic among his family and supporters in attendance.

Their relationship has progressed to official couple appearances at major tournaments. Hasanovic attended both the ATP Finals 2025 and the Monte Carlo Masters and Rome Open, positioning herself as a visible presence in Sinner's professional life. This marks a departure from Sinner's previous relationship with Russian tennis player Anna Kalinskaya, which ended in May 2025 after beginning the prior year.

Sinner's Recent Career Success

The 24-year-old Italian holds the distinction of being the first Italian player to reach the ATP's number one ranking. He has accumulated 19 ATP Tour singles titles and captured four Grand Slam championships: the 2024 and 2025 Australian Opens, the 2024 US Open, and Wimbledon 2025. Additionally, Sinner won the 2024 ATP Finals and claimed the Davis Cup for Italy in both 2023 and 2024.
