January Jones gave birth to a boy! She welcomed son Xander Dane Jones in LA on Tuesday, and both baby and January are "doing great." January kept the sex of her child a surprise throughout the pregnancy, much of which she spent hanging close to home and also practicing yoga. Her series Mad Men is up for many awards at Sunday's Emmys, but it seems unlikely that we'll get to see January on the red carpet so quickly after the delivery. Congrats to January!
