Karaoke with Lohan at David Spade's party.

Lindsay Lohan and the soon-to-be-wed Kid Rock (to Pamela Anderson) play backup to David Spade in a rollicking karaoke trio of "American Woman" during Spade's 42nd birthday bash at Santa Monica's Buffalo Club on Saturday. Lohan, who brought beau Harry Morton, also joined Ellen DeGeneres and Portia DeRossi on Madonna's "Like a Virgin" and Rock's sister on Kelly Clarkson's "Since U Been Gone."
Looks like someone's a karaoke hog. And why is she scratching herself "there" in public? I'll leave it to all your imaginations to think of why Lindsay Lohan might have an ichy coochie.
