Meanwhile, "The Hills" hotties Audrina Patridge, Lauren Conrad and Stephanie Pratt are showing more skin than usual on the red carpet, and we have the saucy pics! Audrina's glam in a thigh-hugging bubble dress, Stephanie's racy in a black bustier number and Lauren's in a daringly low cut frock with lots of gathers. While "I Kissed a Girl" vixen Katy Perry went retro in a vintage ivory corset and pink pumps.
But Ashlee Simpson is stopping traffic with her out-to-there baby bump!
On the boys' side, Rapper Ne-Yo is keepin' it fly in trousers and a fedora and Chris Brown is rockin' white high-tops.
