Ashton Kutcher and Mila Kunis went casual for a walk around their LA neighborhood with their dog yesterday. They've been lying low on the West Coast since returning to California from Italy, where Mila worked on her latest movie. It's been an exciting year for Mila and Ashton, whose relationship became public over the Summer. They traveled to Bali and Australia, popped up in NYC and New Jersey, and were both busy with work. Ashton filmed the Steve Jobs biopic and Two and a Half Men while Mila got in front of the cameras for The Third Person, The Angriest Man in Brooklyn, and Esquire's Sexiest Woman Alive photo shoot. The magazine's title isn't the only one Mila could pick up this year, since she's also in the running for sexiest woman alive in our best of 2012 poll!
