January Jones brought 4-month-old Xander out in LA this afternoon. They stopped by Jamba Juice and later picked up takeout from Panda Express. January's been hanging close to home since welcoming her first child in September, though she was spotted on the set of Mad Men a few times last year. She brought Xander to meet her costars between takes on the series, which recently got a 2012 premiere date. Mad Men will return on March 25 with season five and will hopefully include plenty of Betty Draper moments along with addressing Don's engagement and Joan's pregnancy.
