Katy Perry admits that one of her biggest career mistakes was turning down the chance to work with "boring" Billie Eilish.
In 2016, the E.T singer was told by one of her friends to check Billie out but Katy was less than impressed at the time.
During a Q&A at a private event for Los Angeles based station KIIS-FM, she opened up about the massive fail.
She told the audience that her friend's email read: "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,'" she said.
"Big mistake, huge mistake," she added.
She then joked, "Don't let this hit the internet."
Since 2016 Billie has gone on to win multiple awards, become the youngest singer in history to headline Glastonbury and get a Golden Globe Award and an Oscar for her song No Time To Die which featured as the swan song on Daniel Craig's James Bond.
During the Q&A, Katy wore a pair of light green leather trousers with zips running down the front, which she paired with a collared green and white long-sleeved shirt.
Her trademark black hair was pulled back in an updo with layers falling around and framing her face.
She recently joined Orlando Bloom's ex Miranda Kerr at the 20th G'Day USA Arts Gala wearing a metallic floor-length ballgown skirt.
She matched the skirt with a bralette and wore her hair up, revealing earrings with chain detail.
The event celebrates Australians who are prominent in the U.S entertainment industry.
Katy presented Miranda, who wore a stunning white bodycon dress, with the Excellence in the Arts award.
Miranda went for the classic Hollywood glam look with retro waves and sparkly earrings.
Katy and Orlando started dating in 2016 and got engaged in 2019, before welcoming their daughter Daisy in 2020.
Miranda has spoken about how she and Katy have a strong bond and often spend time together at family events.
