We've heard the reasons why Nick Lachey digs Vanessa Minnillo with such passion. She likes sports, is a guy's gal, yadda, yadda, yadda.

We're guessing the kind of dance moves Minnillo showed off this weekend in Las Vegas don't hurt, either.

With Lachey nowhere to be seen, the former Miss Teen USA spent the even celebrating the release of John Tucker Must Die at Pure Nightclub in Caesar's Palace. The film's leading man, Jesse Metcalfe, was also there.

As reported by TMZ, Minnillo sang and chatted with the crowd, took pictures of herself with fan's cameras and downed what looked like a shot, which she did not seem to enjoy.

Forget who looks better - we'd like to see Jessica Simpson and Minnillo in a dance off, right, fellas?
