Katy Perry has revealed that she would like to collaborate with Bruno Mars.
The Roar songstress said she is very impressed with the Treasure star's versatility because he is "so wildly talented."
She told E! News: " I've always said I'd wanna collaborate with Rihanna, but I'd love to collaborate with Bruno Mars.
"I always say, 'When I grow up, I wanna be the female version of Bruno Mars', because he's so wildly talented in showing everybody that he has so much diversity in him."
The 28-year-old also spoke about her duet with boyfriend John Mayer.
"I got to collaborate with my boyfriend John Mayer. We wrote this song called Who You Love, and it's on his record Paradise Valley. It's a beautiful duet. It's a really lovely song," she said.
Katy will close the iTunes Festival in London on September 30, ahead of the release of her fourth album Prism in October. Her upcoming new single Dark Horse features Jessie J.
"I'm very proud of this record. It's very exciting. It's gonna make you dance, just like the last one but it's a lot more self-reflective," she explained.
