January Jones will "rock" as a mother, according to Christina Hendricks.

The 33-year-old actress is due to give birth to her first child in the autumn - though she has not disclosed who the father of her baby is and her 'Mad Men' co-star expects the blonde beauty will be an amazing mother.

She told People.com: "I'm going to see her next week. She sounds really happy and excited.

"I know January is going to be very warm and tender. I just think she's gonna rock."

January - who is planning to raise her baby as a single parent - was thrilled to get a break from filming recently in order to prepare her house for the impending new arrival but admitted she was disappointed with her lack of cravings.

She said: "I've been enjoying a nice break.

"I've been in a nesting phase just preparing my house and stuff. I've had the luxury of a couple months off.

"I feel great. I haven't had any weird physical side effects. I feel pretty lucky so far.

"Everybody is asking if I've had any odd cravings. I haven't yet. It's a bummer. I wish I had something weird to tell."
