January Jones - New Mum Jones Introduces Mad Men Co-stars To Baby Boy
Actress January Jones took her newborn son to work with her on Tuesday (11Oct11), so she could show him off to her Mad Men castmates.
The new mum was photographed cradling little Xander on her second day back on set, where she introduced the child to co-stars, including John Slattery.
Jones gave birth to the baby boy on 13 September. She has still to name the father of her child - and even left his name off the kid's birth certificate.
