January Jones used to date Ashton Kutcher, who didn’t have any confidence in her, but now she’s a star thanks to Mad Men. Jones said:

"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. So f*ck you! 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."

This isn’t the kind of girl a guy would want to bring home to meet his mother, and Ashton practically married his mother. You can tell Jones is insecure about her star status, because she likes to name drop a lot.
