Paris Hilton at Las Vegas Nightclub Pure: April 7

She gave an impromptu performance of two songs: one from her upcoming album entitled "Fighting Over Me," and a cover of Rod Stewart's "Do Ya Think I'm Sexy?". I think the song choices are very indicative of Hilton's personality, don't you?

She looks like she's having an orgasm when she sings.

With sister Nicky.

Was anyone actually there?? I want to hear how she sounds live!
