The update comes two months after The Kardashians star made an appearance at Beckham Jr.’s ’90s-themed birthday celebration at WSA in New York. For the NFL pro’s big night, Kardashian stepped out in a gothic-inspired black leather dress.

“It was a very fun party with a lot of fun people,” a source told PEOPLE of the event, which was also attended by La La Anthony, Lori Harvey, James Harden, Saquon Barkley, Michael Rubin, Ashley Graham, Emily Ratajkowski, Winnie Harlow, Lil Baby, Emma Chamberlain Luka Sabbat and PJ Tucker.

An insider previously told PEOPLE in September that Kardashian and Beckham Jr. had been “hanging out.” At the time, multiple sources confirmed the NFL pro and his longtime model girlfriend Lauren Wood had officially split. Beckham and Wood share a son, Zydn, whom they welcomed together in February 2022.
