Just a few years ago the closest that Dax Shepard had probably come to scoring with a lead actress was getting naked in front of Jessica Alba on Punk'd. But times they are a changing and now he's a leading man and making out with Liv Tyler on the set of their new film, Smothered. In the movie Dax plays a man who is fired from his job only to have to deal with his mother (Diane Keaton) moving in with him and his wife (Liv) pressuring him for a baby. I love Diane Keaton and we're just glad that Liv came back to work after taking a year off to spend with baby Milo. We've missed her!
