Her perfume commercial is launching right after the VMAs (which I would think would feature her new single?) and she's filmed a VMA commercial, so she'll probably play a substantial role in the show. The single's gotta be coming in the next few weeks.
Katy Perry tweeting Rihanna bit Rihamma will probably served it. I really want my Katy Perry ft Rihanna on Katy's upcoming album. Especially on some type of power "**** every guy out there" ballad.
