Carlos Alcaraz Celebrates U.S. Open Victory at Star-Studded After Party in Manhattan

Carlos Alcaraz attended a private, star-studded after party in Manhattan following his U.S. Open victory over Jannik Sinner, mingling with celebrities, models and members of his inner circle late Sunday night.

Alcaraz defeated Italy’s Jannik Sinner 6-2, 3-6, 6-1, 6-4 in the U.S. Open final on Sunday, Sept. 7, 2025, and later showed up at Chez Margaux, a private supper club in the Meatpacking District, for the Raising Cane’s U.S. Open after party. The event included performances by Cardi B and Kid Laroi and drew a guest list that reportedly included Jamie Foxx, Lenny Kravitz, Tika Camaj, Jessica Alba, Lupita Nyong’o, Adrien Brody, Jon Hamm, Ty Dolla $ign and Kevin Hart.

Photos shared on social media showed Alcaraz posing with fashion model Brianna Bardhi. According to Page Six, Alcaraz dined at Chez Margaux with about 30 close friends at around 10 p.m. after being invited by the club’s owner, Michael Cayre. He was photographed speaking with Raising Cane’s founder Todd Graves and chef Jean-Georges Vongerichten.

Organizers and guests said Alcaraz spent a few hours at the party before leaving in an SUV with a group of people. A brunette seated in the vehicle’s front passenger seat was identified by the Daily Mail as Lucia Martinez, the girlfriend of Alcaraz’s brother, Alvaro. Reports indicated the champion did not partake in legal drinking at the event, although he celebrated with sprayed champagne in the locker room after the match.

The evening’s sightings renewed public interest in Alcaraz’s personal life. Fans began speculating about a relationship between Alcaraz and British player Emma Raducanu earlier in the summer after the two were announced as a team for the U.S. Open’s newly formatted mixed doubles event. Raducanu, 22, said at the time she found the speculation amusing and added, "But I’m glad the internet is having fun and we’re providing some entertainment for everyone," in an interview with BBC Sport. She also said she and Alcaraz have known each other for several years: "We go back a long way and I think that we both started getting to know each other a lot in 2021," and, "... We were like speaking and friends before anyone won anything."

Alcaraz has previously addressed his relationship status in interviews. In a July interview with The Sunday Times, he said, "No, I am single. I am looking for someone," adding that constant travel as a professional tennis player can complicate meeting the right person.

Alcaraz, 22, has maintained a high public profile both on and off the court since rising to prominence, and his appearances at social events following major victories continue to draw media attention. He is scheduled to appear at post-tournament commitments and promotional events customary for Grand Slam champions, while the tennis calendar progresses toward the next tour events.
