Who will take home Emmys this year?
January Jones is officially a mommy!

The 33-year-old Mad Men actress welcomed a healthy baby boy on Tuesday, her rep confirmed to Us Weekly. Back in April, JanJo shocked fans when she confirmed fans that she was pregnant, but would not reveal the identity of the father.

We have a feeling she won’t be attending Sunday’s Emmys ceremony!

January plays Betty Draper on the hit AMC show Mad Men, which is nominated for a slew of Emmys.

All throughout her pregnancy, January was very serious about exercise, and went to yoga nearly every day!

Congrats to the new mom!
