Walker and his younger brother Cody posed together at the Flags of Our Fathers Los Angeles premiere in October 2006. "Both go back to my childhood and I have some of the sweetest memories there," he said of his favorite memories during an August 2011 Cosmopolitan interview. "I'd bottle my biggest memory, which when my daughter was born – that was exciting. Another is when I went on a snowboarding trip with some friends." Walker is a dad to 15-year-old daughter Meadow, from ex Rebecca.
