January Jones was in costume yesterday to shoot Mad Men in LA. It was her first day back on set since welcoming son Xander Dane Jones, who arrived in the world on Sept. 13. January skipped out on the Emmys, as they were just a few days after his birth. Mad Men, nonetheless, went on to win best drama for the fourth year in a row! Prior to Xander entering the world, January had been laying low and nesting to get ready for motherhood. Now that she's back on set with her costars Jon Hamm, Christina Hendricks, and Elisabeth Moss, we're, hopefully, inching close to their show's return to AMC next year.
