Mad Men welcomed a very special guest this week – January Jones’s new baby boy!

The proud mom, 33, brought her 4-week-old son, Xander Dane Jones, to the set of her AMC drama on Tuesday. She was reportedly smiling from ear to ear as she introduced him to John Slattery and a few other cast members.

Xander, born Sept. 13, is Jones’s first child.

Mad Men recently began filming its fifth season, due to premiere in 2012.
