Katy Perry, Taylor Swift, And John Mayer Were All At Drake's Birthday Party

Today, October 24th, Drake turns 30 years old. Yes, the same 15-year-old you used to watch on Degrassi as Jimmy Brooks has now grown to be one of the most popular rappers on the planet, and has officially joined the 30 club. And to celebrate, he threw a star-studded bash inviting many of his celebrity friends -- including Taylor Swift, Katy Perry, and John Mayer. That's right. All three in the same room. 

The party went down at Delilah in Los Angeles over the weekend on Sunday, October 23rd. According to Us Weekly, Taylor showed up to the celebration with Karlie Kloss and the HAIM sisters, rocking a black bandeau and leather skirt. And this cute flash tattoo:

Katy, also wore black, complimenting her dress with a very sparkly choker. And Us Weekly reports that Katy and John did exchange words, however the conversation between the exes was short. A source tells Us, "Katy and John did talk to each other. But the conversation wasn't for long."

As we know, John dated both Taylor and Katy. He dated Taylor back in 2009, while he and Katy were on and off for two years since 2012. And following the release of her album 1989, Katy and Taylor's feud came to light after she revealed her song "Bad Blood." 

Also at the party to celebrate Drake's big 3-0 were Jamie Foxx, French Montana, and (of course) the rapper's parents. His father, Dennis Graham, even sang him happy birthday. 

HAPPY BIRTHDAY, DRAKE!
