Listen to Katy Perry Radio only on iHeartRadio

Katy Perry spent the weekend entertaining KatyCats at her Katy Perry pool party in LA, and the pop star got a little frisky when she sat down to chat with San Francisco's WiLD 94.9 DJ Nessa.

Katy chatted about her upcoming 3D concert film (she goes sans make-up!), dodged multiple questions about sex (she's a 'good Christian girl'!) and finally made every guy's dream come true when she said she's like to, ahem, you know, with her gal pal Rihanna.

Nessa: Are you and Rihanna ever gonna put music our together?

Katy: No, but we're gonna have sex.
