It's a boy for the Mad Men star.
January Jones, 33, welcomed her first child on Tuesday, her rep tells Lifeline Live. His name: Xander Dane Jones.
(Jones has never gone public with the father of the baby.)
According to babynamesworld.com, Xander is of Greek origin and means "defending men." Sounds like superhero material to us.
Mother and child are "doing great," the rep tells Lifeline Live.
