Katy Perry says one of her biggest regrets is turning down a Billie Eilish collaboration.
The 38-year-old singer revealed she was approached about working with Billie, 21, before she became a huge star but Katy turned down the offer.
In a TikTok posted by 102.7 KIIS FM, Katy can be seen explaining: ”Someone sent me an email one time that was: ‘Hey, check out this new artist. I’d really like us to work with her because she was working with me for Unsub [Records].
“It was a song called Ocean Eyes, and it was just a blonde girl. And I was like, ‘Meh, boring.’
“Big mistake. Huge mistake. Don’t let this hit the Internet.”
