The 28-year-old 'Roar' hitmaker, who admires the 'Treasure' singer, hopes she get to work with him on a track, reported E! Online.
"I've always said I'd wanna collaborate with Rihanna, but I'd love to collaborate with Bruno Mars," Perry said.
"I always said, '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," she added.
Mars' two albums, 'Doo-Wops and Hooligans' and 'Unorthodox Jukebox', have received critical acclaim. Pery recently announced that her next release 'Walking on Air' from her upcoming album Prism will hit iTunes on September 30.
