Taylor Swift and Katy Perry are still having a cold war of sorts. The two singers, who feuded a long time ago, aren't on talking terms yet and this became evident at Drake's 30th birthday party.

The Blank Space singer, who isn't usually seen at Drake aka Drizzy's legendary birthday parties, decided to hang out with friends and let her hair down. However, she remained seated at her table when she realised that Perry and her ex, John Mayer, were also present at West Hollywood's newly opened club Delilah on Sunday, October 23.

A source said that Swift politely ignored Perry and Mayer and mostly hung out with her friends. "She didn't want to make a big scene and leave when she saw they were there too," the source added.

Indeed, the many pictures from Drake's party don't include Swift and Perry in the same frame. The 26-year-old singer reportedly hung out with her friends Karlie Kloss and the Haim sisters.

According to a US Weekly article, Perry didn't mind Swift's presence at the party. The Roar singer reportedly spoke to Mayer, who she dated for many years before calling it quits.

"John approached Katy and they talked – they're on good terms. Seeing John is like seeing an old friend," the source added.

Although Perry didn't mind Swift's presence at the party, the singer did throw some shade at the Out of the Woods singer. 

The 31-year-old singer shared a video of her dancing to West's lyric, "I feel like me and Taylor might still have sex why? I made that b**** famous," at his recent concert in Los Angeles. Perry's video went viral on Twitter, with many fans commenting on the feud between her and Swift.

Swift and Perry's feud began when the Rise singer signed three of Swift's backup dancers for her world tour.

During an interview with Rolling Stone, Swift said, "She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me... So now I have to avoid her. It's awkward, and I don't like it."
