During last weekend's iHeartRadio Music Festival in Las Vegas, Katy Perry spilled that she'd like to collaborate on a track with Bruno Mars.

"I've always said I'd wanna collaborate with Rihanna, but I'd love to collaborate with Bruno Mars," Perry told E! News. I always say, 'When I grow up, I wanna be the female version of Bruno Mars,' cause he's so wildly talented in showing everybody that he has so much diversity in him."

In other news, Katy announced that her next single from her album "Prism" (due Oct. 22) will be "Walking On Air", set to hit iTunes Sept. 30. She told E!, "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."

Gotta admit, the idea of a Perry/Mars collab sounds pretty appealing! What do you think?
