Katy Perry has revealed that she wants to have sex with Rihanna, and added that she would never make love while listening to her own music.
The 27-year-old singer split from husband Russell Brand in November.
When asked if she would ever collaborate with her close friend Rihanna, the singer ruled out working on a record with the star, but she joked that they would do something more intimate instead.

"No, but we're going to have sex," Contactmusic quoted her as telling US radio station Wild 94.9.
When further enquired if she listens to her own music while she is having sex, Perry claimed that it would be "over the line."
"I'm not a narcissist! OK, I'm a narcissist, but that would be over the line. Having sex to your own song, that's horrible. I'm a good Christian girl," she said.
As the raunchy conversation continued, the former American Idol judge was questioned on whether she has ever had a threesome but the star only said "no comment."
Perry, who has previously confirmed that she will collaborate on a song with Rihanna, had said that she wants to make sure it is "iconic.""It's one of those things that's got so much build up that we have to deliver... I definitely want to do something that is so iconic. We're both busy but we planted the seed two years ago. How disappointed would you be if that song came out and it's no good," she added.
