Jannik Sinner, currently ranked world no. 1 and a favorite to win this year’s U.S. Open, is dating fellow tennis player, Anna Kalinskaya (currently at a career high world no. 15).

“You know, I don’t like to talk much about my private life,” Sinner said at the French Open. “Yes, I’m with Anna, but we keep everything very confidential. I won’t say more.” As Sinner plays in the Open quarterfinals this evening, take a look back at the brand-new tennis power couple’s relationship history:

They started dating sometime in 2024.

Sinner was previously linked to model Maria Braccini as recently as earlier this year. Rumors that Sinner and Kalinskaya were together went into overdrive when Sinner took a photo with a fan in Monaco in mid-May. Fans then reportedly zoomed in to his phone screen to see he was on a call with Kalinskaya. After, they were photographed by paparazzi getting dinner in Paris ahead of Roland Garros.

At the French Open, after his first round match, Sinner confirmed he’s seeing Kalinskaya, but declined to share any other details on their relationship, citing their privacy. During the tournament, they’re pictured practicing together and watching each other’s matches.

Both Sinner and Kalinskaya had strong runs at the same time, reaching the finals of the tournaments they’re playing in—the Halle Open and the Berlin Open, respectively. Before the finals, Kalinskaya said, “I’m just trying to be a little bit as good as [Sinner].” She added, “I’m gonna text him now, I’m so happy.”

Sinner then went on win the Halle Open, while Kalinskaya lost in the finals of the Berlin Open. After Sinner’s win, he told the crowd during an on-court interview, “My girlfriend Anna played in Berlin today. She lost, with six match points. So I’m very sorry for her. She also had an amazing week.”
