January Jones will be a Great Mother-- Mad Men Costar

January Jones‘s latest pregnancy publication may have come as a surprising to some – but not essentially to folks close to her.

The actress, who is expecting her first child in the collapse, has talked about wanting to grow to be a mother for some time.“It’s amazing that she’s sought to do and that she’s thrilled to do,” Jones’s Mad Men costar Aaron Staton told , The Creative Coalition and WWE’s “be a STAR” launch in Washington, D.C. on Friday.

“January is sweet person,” Staton said. “I believe she’s a sincere person. I think she’s truly going to be a big mother.”

Staton, who is dad to 10-month-old son Beckett, doesn’t think Jones, 33, will need much advice when it comes to maternity. So much of it is natural, he said. “It’s sort of intimidating, but so much of it comes naturally when you meet the kid.”
