U.S. Open champion Carlos Alcaraz is dating Sports Illustrated Swimsuit model Brooks Nader, her younger sister, Grace Ann, revealed to E! News on Wednesday (September 10).

“The rumors are true,” she said. “Dating is such a loose term. But I do know he’s the man of the hour.”

Grace Ann said she hadn't yet met Alcaraz, 22, but was dying to, adding that he's "such a cutie" while discussing the recent U.S. Open champion, though her sister nor the Spanish tennis star have yet to publicly confirm their relationship. Brooks, 24, attended the U.S. Open trophy presentation after Alcaraz defeated Jannik Sinner in four sets, 6-2, 3-6, 6-1, 6-4, in Flushing, New York, on Sunday (September 7).

The Sports Illustrated Swimsuit model was previously rumored to be dating Sinner after attending an earlier match at the Grand Slam event.

“Is this like an interrogation? I’m so scared right now,” Nader said during an appearance on Jimmy Kimmel Live last week when asked by the host if she was dating Sinner.

“Well, ask Stephen [Colbert] what match we were at,” Nader said, referencing the talk show host who she was sitting next to in a suite on August 31. “I don’t think he was playing in that one. You’re close, you’re warm.”

Kimmel then asked if she was seeing "somebody else" to which she replied "You're warm, but we weren't at that match."

Alcaraz had previously been linked to fellow tennis player Emma Raducanu this summer when the two teamed up in the newly formatted U.S. Open mixed doubles event in June before telling the Sunday Times that he was looking for "the right person" in July.

“No, I am single. I am looking for someone,” he said at the time. “It can be difficult as a tennis player to meet the right person because you are traveling all the time.”
