At the Roosevelt Hotel last night, the cyber world embraced Hollywood (and reality television, apparently) at the NYLON and MySpace Young Hollywood Issue Party. Hosted by Kat Dennings and Olivia Thirlby, it looked like everyone who couldn't fly out to the East coast for the Costume Institute Gala was there (and everyone who wouldn't have been invited anyway). Sophia Bush, Rumer Willis, Ryan Eggold, and Kellan Lutz were holding up the acting portion with Jack and Kelly Osbourne and Nicky Hilton were just some of the rich-kid sector.

Dominating the party, however, was the MTV reality TV attendance list: Audrina Patridge, Stephanie Pratt, Lo Bosworth, Kelly Cutrone, and even Laguna Beach alum, Kristin Cavallari was there (where was Lauren Conrad we wonder?). Also represented was a massive amount of plastic surgery and botox.
