It’s a small world after all — well, at least in Hollywood.

Taylor Swift and Katy Perry were in attendance at the 30th birthday celebration for Drake in Los Angeles on Sunday night, as well as their shared ex, John Mayer, a source tells PEOPLE.

Swift arrived early to the birthday bash — which brought together 150 of the rapper’s closest family and friends at the h.wood group’s Delilah — and had several girlfriends in tow, including model Karlie Kloss and the Haim sisters.

It’s unclear whether Swift crossed paths with Perry, whom she reportedly wrote “Bad Blood” about, or Mayer, who is rumored to have inspired the pop star’s 2010 song “Dear John.”

Perry also dated Mayer for several years before finally calling it quits in July 2015.

In a video from the festivities, Drake told his parents and guests of entering his thirties, “People keep asking me how I feel, and I feel, I feel great.”

“I want to thank everybody for tonight, it’s an incredible evening,” he added.

Other partygoers, who enjoyed Drake’s whiskey Virginia Black, included Jamie Foxx, Zoe Kravitz, French Montana and Pretty Little Liars star Shay Mitchell.

Noticeably absent? Drake’s on-again-off-again girlfriend Rihanna. Despite breakup rumors earlier this month, a source told PEOPLE the couple was still together but in an “open” relationship.
