Owen Wilson wandered through a Malibu farmers market with his son, Robert, yesterday. Owen's back in California after popping up in Atlanta last month for work. He filmed The Internship with Vince Vaughn and both guys brought their kids to the set. Little Robert and Vince's young daughter, Locklyn, hung out behind the scenes when their parents weren't busy in front of the cameras. Owen has since moved on to his next project, voicing Reggie in the animated comedy Turkeys. He also has a birthday coming up, too, and will turn 44 on Nov. 18.
