Taylor Swift, John Mayer, and Katy Perry All Attended Drake’s 30th-Birthday Party

Say what?

It was an A-list crowd at Drake’s 30th birthday party.

The rapper celebrated his milestone birthday in Los Angeles on Sunday, and those in attendance included Katy Perry, Taylor Swift, and John Mayer, People reports.

That’s surprising, given that Taylor Swift and Katy Perry have been noted rivals in the past — Swift’s “Bad Blood” is reportedly about the other pop star. They have also both dated Mayer.

It’s unclear if Swift interacted with either of her music rivals at the event.

“Katy and John did talk to each other,” an insider told Us Weekly. “But the conversation wasn’t for long.”

Good times !! @johnmayer #happybirthday aubrey @champagnepapi

Drake had 150 friends and family at the bash, and Swift brought a posse that included model Karlie Kloss and the sisters who make up the band Haim, according to People’s sources.

Other notable attendees included Jamie Foxx and Zoe Kravitz. Close Drake collaborator Rihanna was, however, noticeably absent.

She missed the party because she was busy in New York City filming for her upcoming heist film, Ocean’s 8.
