OMG Famous

Xander Dane Jones!

That's the name "Mad Men" star January Jones gave to her son, who was born on Tuesday, according to Us Weekly and other outlets.

"Mom and baby are doing great," Jones' rep said. 

We were kind of hoping that the 33-year-old actress would reveal the identity of the child's father upon his birth, but, alas, no such luck.

Jones announced her pregnancy in April.
