Although the pair's feud was first revealed in 2014, with reports that Taylor's 'Bad Blood' was inspired by her rivalry with Katy, the 'Firework' hitmaker has asked Taylor to attend her Spotify party in Los Angeles on Saturday (13.02.16).

Revealing that she has also invited Adele, who like Taylor has withheld her music from Spotify's streaming service, Katy said: "It's just up to their schedules."

Katy also revealed that her party, which she referred to as the "Met Ball of music", is only for "creators" and no managers, journalists or publicists are allowed.

She told the New York Times: "They are not creators. 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.

"You have to be a creator - it's artists, producers and songwriters. And it's a mixture of new and familiar artists, a combination of the past two years' Grammy nominees and also [acts] from the Spotify Discover playlist. It's Kacey Musgraves, Karen O, Miguel, Tove Lo, Shirley Manson, Max Martin. Then up-and-coming songwriters like Blood Pop and Bonnie McKee all under the same roof as Diane Warren. In some ways, I'm trying to start the Met Ball of music."
