Ali Larter Pictures With Son Theodore MacArthur in Santa Monica

Ali Larter held her baby son Theodore yesterday while out for a walk in LA! The adorable duo explored the streets of Santa Monica, and Theo alternated between being in Ali's arms and resting in his stroller. Ali and her husband, Hayes MacArthur, welcomed little Theodore six months ago in late December. The happy couple has since been all about their bundle of joy, though Hayes focused on work for a bit to shoot his now-cancelled NBC series Perfect Couples. Ali is easing back into the Hollywood social scene and recently stepped out for a photography opening at the Annenberg Space For Photography as well as a Chanel-sponsored NRDC fundraiser earlier this month. Her next big screen appearance will be in Resident Evil: Retribution, the followup to 2010's Resident Evil: Afterlife with her costar Milla Jovovich.
