Jannik Sinner is currently dominating the tennis world, but as his trophy cabinet grows, so does the public curiosity regarding his life away from the baseline. Since the latter half of 2025, one name has been consistently linked with the Italian star: Laila Hasanovic. As the 2026 tennis season enters its high-stakes clay-court swing, the partnership between the multiple-time Grand Slam champion and the Danish model has become one of the most talked-about dynamics in professional sports.

The relationship between Sinner and Hasanovic represents a significant chapter in the life of a player who has historically been guarded about his privacy. Unlike the fleeting rumors that often surround high-profile athletes, this connection has been solidified through public acknowledgments and frequent appearances at the tour's most prestigious venues. Understanding who Laila Hasanovic is requires looking beyond her role as a supportive partner in the player's box, as she maintains a successful career and a distinct identity in the world of fashion and digital influence.

The Background of Laila Hasanovic

Born in November 2000 in Copenhagen, Denmark, Laila Hasanovic brings a cosmopolitan flair to Sinner’s circle. Of Bosnian heritage, she was raised in the Danish town of Svendborg before her career took her across the globe. Her rise to prominence in Denmark began in her late teens when she became a finalist in the Miss Denmark 2019 pageant. This early success served as a springboard into the competitive world of international modeling.

Hasanovic is not merely a figure associated with sports stars; she is a professional who has worked with some of the most iconic brands in the industry. Her portfolio includes significant work with Armani Beauty, and she has been a recurring presence at major fashion events, including the Venice Film Festival. In late 2025, her professional stature was highlighted when she was referred to as a muse for high-fashion campaigns, demonstrating her ability to navigate the demanding atmosphere of European fashion capitals while Sinner navigates the ATP circuit.

Beyond traditional modeling, Hasanovic has cultivated a substantial digital presence. With hundreds of thousands of followers across Instagram and TikTok, she has built a brand centered on lifestyle, travel, and beauty. This digital savvy has made her a prominent influencer, though she has notably managed to balance her public-facing career with the discretion that Sinner values in his personal life.

The Official Confirmation in Vienna

While rumors of their involvement began to circulate during the summer of 2025, particularly after they were spotted together in Monte Carlo, it was the Vienna Open in October 2025 that marked the "hard launch" of their relationship. After clinching the title in a hard-fought final, Sinner used his victory speech to acknowledge the people closest to him. While he has often kept his speeches focused on his team and parents, this occasion was different.

During the ceremony, Sinner explicitly mentioned his "girlfriend" while thanking his support system for their patience and effort in understanding the demands of his career. Hasanovic was seen sitting alongside Sinner’s parents, Siglinde and Johann, signaling that she had been integrated into his inner circle. This public acknowledgment was a rare move for Sinner, who previously told Italian media that he prefers to keep his private life protected to ensure the well-being of those he loves.

Supporting Sinner Through Major Milestones

Since the Vienna announcement, Hasanovic has become a fixture at Sinner's matches. Her presence in the player's box is often noted by broadcasters and fans alike, especially during high-pressure moments. She was notably present during Sinner’s victory at the 2025 Nitto ATP Finals in Turin, where she joined him on the court for the trophy celebrations. The image of the couple together on home soil in Italy resonated deeply with fans who have followed Sinner's journey since his teenage years.

In early 2026, as Sinner defended his title in Melbourne, Hasanovic was again a pillar of support. The demands of a Grand Slam—two weeks of intense physical and mental exertion—require a stable environment, and Sinner has hinted that his current relationship provides that balance. Despite the media spotlight, the couple has avoided the "paparazzi" lifestyle, opting instead for quiet support rather than grand public gestures for the cameras.

The Monte Carlo Connection

When not traveling for tournaments, the couple spends much of their time in Monte Carlo, the Mediterranean principality that serves as home to many of the world's top tennis players. Local reports have painted a picture of a grounded couple who enjoy the simple pleasures of the region. They have been spotted frequently in the La Condamine district, often visiting local spots like a well-known gelato shop where Sinner, a self-proclaimed ice cream lover, is a regular.

Neighbors and locals describe them as a "serene" and "kind" couple who integrate easily into the community. This lifestyle aligns with Sinner's grounded personality; despite his multi-million dollar earnings and global fame, he has remained consistent in his preference for a low-key existence. Living together in Monte Carlo has allowed them to build a sense of normalcy away from the hectic schedule of the ATP Tour, which often sees players traveling for over 40 weeks a year.

Sinner’s Philosophy on Love and Tennis

Jannik Sinner’s approach to his relationship with Laila Hasanovic is best understood through his own words regarding the difficulty of being a professional athlete. In various interviews, including a notable feature in Vanity Fair, Sinner has discussed the complexities of dating while being a top-ranked player. He has acknowledged that his focus during tournaments is absolute, often making it difficult for a partner to feel prioritized.

However, Sinner has also matured in his view of relationships. He has observed that many of the greatest players in history—Federer, Djokovic, and Nadal—all maintained stable, long-term relationships that contributed to their longevity. For Sinner, finding "the right love" is not a distraction but a foundational element that allows him to compete at his best. He views a partner who understands the sacrifices of the sport as an asset rather than a hindrance.

This maturity is reflected in how he and Hasanovic manage their public image. They rarely post about each other on social media, choosing instead to keep their intimate moments private. This strategy has allowed them to avoid the intense scrutiny that has affected other "tennis power couples" in the past. By keeping the focus on their respective careers while supporting each other behind the scenes, they have managed to maintain a healthy dynamic.

Previous Relationships and Context

To understand the stability of Sinner's current relationship, it is helpful to look at his previous dating history. Sinner was formerly in a long-term relationship with Italian model Maria Braccini, and more recently, he was linked to Russian tennis player Anna Kalinskaya. The split from Kalinskaya in early 2025 was handled with his trademark discretion, but it was clear that the transition to his relationship with Hasanovic marked a new chapter in his personal life.

Hasanovic also brings her own history to the relationship, having previously dated Formula 1 driver Mick Schumacher. Her experience in the high-stakes world of elite motorsport likely prepared her for the unique pressures of dating a top-tier athlete. The world of F1, much like the ATP Tour, involves constant travel, intense media scrutiny, and a relentless schedule. This shared understanding of the "elite athlete lifestyle" is likely one of the factors that makes their current partnership so resilient.

The Role of the "Tennis Partner"

The role of a partner in professional tennis is often underestimated. Beyond the visible support in the stands, they provide the emotional stability required to navigate the highs of victory and the lows of defeat. For a player like Sinner, who operates with a highly methodical and disciplined team, having someone outside of the technical staff to provide a different perspective is invaluable.

Hasanovic’s own career success is also a critical component. As a model and entrepreneur—she has explored launching her own beauty brands—she understands the importance of ambition and professional drive. This mutual respect for each other’s careers creates a balanced dynamic where neither party is overshadowed. While Sinner is the face of Italian tennis, Hasanovic is a prominent figure in the Danish and international fashion scenes in her own right.

Looking Ahead to the Rest of 2026

As the 2026 season continues, with the French Open and Wimbledon on the horizon, fans can expect to see Laila Hasanovic remains a constant presence in Sinner’s box. Her influence seems to be a positive one; Sinner has played some of the best tennis of his career since they went public. The calmness she brings to his off-court life appears to translate into the composed, ice-cool demeanor he exhibits during five-set thrillers.

While the media will always be hungry for more details about their private life, Sinner and Hasanovic seem content to let their actions speak for themselves. Whether they are walking the streets of Monte Carlo or standing on the podium at a Grand Slam, they represent a modern version of a sports power couple: successful, stylish, and fiercely protective of their personal bond. For Jannik Sinner, having Laila Hasanovic by his side isn't just about romance; it's about having the right support system to stay at the very top of the world rankings.
