January Jones, who plays Mad Men's Betty Draper, didn't have a lot of support from ex-boyfriend Ashton Kutcher when she tried to get into acting. "He was like, 'I don't think you're going to be good at this,'" Jones tells GQ. "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." (Photo: WENN)
