Paris Hilton hit up the Scream 2007 awards this weekend -- but was booed when she stepped on stage!
Hilton was at the horror themed awards, which airs tomorrow at 10:00 PM on Spike TV, introducing a clip from her new flick "Repo! The Genetic Opera," joined by her co-stars Bill Mosely and Anthony Stewart Head. Once she started speaking, a few audience members starting booing Hilton over the applause.
Hilton played it cool -- and according to the guys at horror movie blog Bloody Disgusting, the audience was actually cheering after they saw the clip from the upcoming sci-fi musical.
