Perez Hilton's 'One Night In Chicago': Kid Sister, B.O.B. And LOTS Of UV Vodka (PHOTOS)

Gossip blogger Perez Hilton headed to Chicago Thursday to kick off Lollapalooza with a big, bright and loud party at the Hard Rock Hotel.

Hilton's "One Night In Chicago" featured performances by Chicago's own Kid Sister, Nneka, J. Brazil, Lissie and B.O.B. The place was also packed with Chicago bloggers, reporters and fans lucky enough to win tickets to the event.

The party was presented by DROID X by Motorola, UV Vodka, Express and vitaminwater--and guests seemed quite pleased with the tasty UV/vitaminwater combos the bartenders came up with.

Needless to say, it was a fun night. DarkRoomDemons shared some of their photos of the event with us. Check them out:
