January Jones debuted red hair while out in LA yesterday. She arrived at a friend's Malibu home for a party along with her baby son, Xander Jones. It was Father's Day, and just a few weeks earlier, January and Xander spent Mother's Day, their first, together. January's new red hair color comes during a break from working on her AMC series, Mad Men, in which she plays blond-haired Betty Draper. The hue wasn't the only change. It seems January also added extensions, since at last week's Young Hollywood Awards, she was still sporting her shoulder-length blond locks.
