January Jones Gives Birth To A Boy

Mad Men star January Jones, 33, gave birth to a baby boy on Tuesday. Jones, who named her new bundle of joy Xander Dane Jones, has not revealed who his father is. Before Tuesday, the X-Men: First Class star had also not revealed the sex of the child — even to herself. "It's going to be a surprise for me," she told People in June.

Jones has not entertained much speculation about the father's identity. She previously dated Josh Groban and Ashton Kutcher, but was most recently linked with Saturday Night Live comedian Jason Sudeikis, who joked about becoming a father when he hosted the MTV Movie Awards in June. “I might be a dad soon,” Jason said during the show. “I have a lot of pressure on me, OK?”

Rumors also circulated that X-Men director Matthew Vaughn could be the father, but he denies it.
