Taylor Swift 's breakup with Spotify was very public, and her rumored rift with Katy Perry played out in the spotlight, too.

But is any type of bad blood in the past now? Well, a certain California Gurl revealed to the New York Times that she's co-hosting a private artists-only party on Saturday in lieu of attending the 58th Annual Grammy Awards on Monday... Spotify is sponsoring the event, which Katy is billing as "An Evening to Celebrate the Creators"—and guess who's invited? T-Swift, yes, also Adele (who limits the songs from her catalog she allows on streaming services).

Indeed, Katy confirmed to the NYT that both ladies are invited to her get-together. "It's just up to their schedules."

The guest list reportedly includes about 250 people, none of whom will be managers or publicists. "They are not creators," Katy explained. "They're important to the creation, but it's only artists, producers and songwriters. There's a press opportunity in the front, like a red carpet, but if you want to be more low-key you can arrive via garage. I'm trying to keep it as pure as possible because in the eight years that I've been going to these things, I am just always so exhausted."

Katy has attended the past eight Grammy Awards, but this year, she's looking forward to watching this year's from home. "In my pajamas, eating matzo ball soup," she told the NYT. "No makeup, glad I'm not in a corset. Vicks cream on."
