January Jones GQ cover

Mad Men star and America’s sexiest housewife, January Jones has the perfect name for a cover girl.

Jones, who appeared with Jack Nicholson in the film Anger Management, says the actor watched nearly the entire first season of Mad Men without realizing that she was Betty Draper.

“That was pretty awesome, she says of getting the call from Nicholson. “It was a kind of vindication, especially since not everyone in Hollywood has always been so positive.”

One big name that wasn’t so supportive was ex-boyfriend Ashton Kutcher.

“The guy I was dating when I first got to L.A. was not supportive of my acting,” she says. “He was like, I don’t think you’re going to be good at this…He only has nice things to say now—if anything, I should thank him. Because the minute you tell me I can’t do something, that’s when I’m most motivated.”
