Ali Larter held his young son Theodore yesterday while he was out for a walk in Los Angeles! The duo explored the lovely streets of Santa Monica, and Theo alternated between being in the arms of Ali and rest in the stroller. Ali and her husband, Hayes MacArthur, welcomed little Theodore six months ago at the end of December. The happy couple has since been everything in their bundle of joy, of Hayes's work focused on something to make his now canceled NBC series perfect couple. Backlight of Ali in the Hollywood social scene, and has recently released a photograph in the opening Annenberg Space for Photography and a Chanel-sponsored NRDC fundraiser earlier this month. His next big screen appearance will be in Resident Evil: Retribution, monitoring of 2010 Resident Evil: Afterlife Milla Jovovich with her costar.
