Katy Perry and Rihanna look like they are having a good time ;) They were at a birthday party in New York City. What is up with Katy's Madonna boobies bra?! Yikes! Ha! I just saw her phone in her boob! I have friends that do that. I've heard it's not good to keep the phone so close/touching your boob.....Is that a myth or fact? Any doctors in the house?
