ShoWest is a film trade show held in Las Vegas every year so that studios can sell their movies. Zac Efron, a resurfacing Rachel McAdams, Michael Caine, Dennis Quaid (and, of course, a flop film) plus wife Kimberly, Audrey from the Hills, Briana Evigan, and other celebs attended the Sin City fete.

Dennis Quaid has supposedly settled down with his new wife and adopted twins, but things are not always as they appear. Here’s Dennis and wife partying at the Playboy mansion. Dennis looks a bit wasted, don’t you think?

Here he is in Las Vegas sans wife hanging out with porn star Mia Foxx.

Rumor has it that when he was playing a charity golf tournament last year in South Carolina, he frolicked with some locals in a bar. They turned out to be some women who were part of a bridal party. Quaid allegedly took one of the ladies back to his hotel room.
