It would be somewhat of a surprise if Taylor Swift went to Katy Perry's party this weekend.
However, as Perry tells it, the invite is out there. While the "Dark Horse" singer is not attending the GRAMMYs this year, she is hosting "An Evening to Celebrate the Creators," which is billed as an event for artists and producers to connect, free from publicists, managers, and press, and is taking place on Saturday night ahead of Monday's awards show.
Spotify is a sponsor of the event, and despite the fact that Swift and Adele have both withheld their music from the streaming service, they are both welcome to the party.

"It's just up to their schedules," Perry told the New York Times on Thursday.
Swift's presumed feud with Perry dates back to a Rolling Stone interview Swift gave in 2014 about a fellow artist.
"For years, I was never sure if we were friends or not," Swift told the magazine. "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'"
Shortly after the article was published, Perry tweeted a Mean Girls reference: "Watch out for the Regina George in sheep's clothing..."

Perry would later confirm to Billboard the tweet was about Swift, saying, "If somebody is trying to defame my character, you're going to hear about it."
Afterward, many people assumed Swift's song, "Bad Blood," was directed at Perry. However, Swift maintained to GQ last October that the single is just about "losing a friend," adding, "I never said anything that would point a finger in the specific direction of one specific person, and I can sleep at night knowing that."

Meanwhile, Perry aside, Swift is currently wrapped up in some re-ignited drama with Kanye West, after the rapper referenced her on his new album, saying: "I feel like me and Taylor might still have sex, I made that b**ch famous."
While Swift's reps claims the singer "cautioned [West] about releasing a song with such a strong misogynistic message," West took to Twitter, countering that not only was the line not meant as a diss, but that Swift inadvertently came up with the line herself.
