Jannik Sinner Steps Out With Alleged “New” Girlfriend in Monte Carlo Winding Anna Kalinskaya Split Speculations
Jannik Sinner, the world No. 1 tennis star, sparked widespread speculation about his personal life in April 2025 when he was spotted in Monte Carlo with Russian model Lara Leito, fueling rumors of a new relationship and confirming whispers of a split from fellow tennis player Anna Kalinskaya. The sighting, reported by outlets like *La Gazzetta dello Sport* and *EssentiallySports*, came as Sinner prepared for his return to competitive tennis at the Italian Open following a three-month doping suspension that ended on May 4, 2025. The Italian, who had been sidelined since February 9, was seen walking with Leito, a 31-year-old known for her modeling work with *Vogue* and *L’Officiel*, toward a practice session, igniting social media buzz.
Sinner and Kalinskaya’s relationship, which began around April 2024 and was confirmed publicly during the 2024 French Open, had been a fan favorite. The couple shared notable moments, including a kiss after Sinner’s 2024 US Open victory. However, by late 2024, signs of strain emerged. They unfollowed each other on Instagram, and Kalinskaya was absent from Sinner’s box at the 2025 Australian Open and ATP Finals, opting instead for a Miami vacation during the latter. Sinner’s comments in November 2024, when he told *Esquire* that having a girlfriend “either makes you feel good or makes you feel bad” and that he “cannot afford to change,” further stoked breakup rumors.The Monte Carlo sighting with Leito, who reportedly dated actor Adrien Brody previously, appeared to confirm the end of Sinner’s romance with Kalinskaya. Posts on X amplified the news, with users like @TennisUpToDate2 stating, “Jannik Sinner’s relationship with Anna Kalinskaya is seemingly over as World No.1 reportedly dating Russian mode
