January: 'Men' Premiere!
January Jones stuns on the red carpet.
Talk about one hot baby mama!

Mad Men beauty January Jones arrived in style at JFK airport on Saturday, where she held onto her 6-month-old son Xander as she made her way past cameras.

January has been busy promoting the upcoming -not to mention long-awaited – fifth season of Mad Men, which (finally!) kicks off this Sunday, March 25, at 9PM. Celebuzz was on the scene at the season 5 premiere last week in LA, where we talked to stars Jon Hamm and more about what fans can expect from the show. Read more about it here!

January gave birth to Xander Dane Jones on Sept. 13, 2011. Xander’s father has yet to be named.
