Jennifer Garner, James Franco, Mila Kunis, and Johnny Depp were among the stars who stepped out for the Walt Disney Studios CinemaCon event in Las Vegas on Tuesday evening. It was Jennifer Garner's first event since giving birth to Samuel, her first son with husband Ben Affleck, at the end of February. She also celebrated her 40th birthday earlier this month and was looking fantastic on the red carpet in Dolce&Gabbana. James Franco and Mila Kunis were both out to start promoting Oz: the Great and Powerful. Mila is currently the center of attention since she's rumored to be dating Ashton Kutcher, who was her costar on That '70s Show. Ashton and Mila reportedly spent a romantic weekend together recently, but their reps denied they were a couple. Johnny Depp was out to represent Dark Shadows, which is coming up right around the corner, hitting theaters on May 11.
