Ashton Kutcher, January Jones

Ashton Kutcher was the famous member of the couple when he and "Mad Men" star January Jones first began dating in 1998. After three years together, they split -- and he moved on to a much bigger name, Demi Moore. But Golden Globe nominee Jones is having the last laugh. In a 2009 interview with GQ, she revealed that an ex, believed to be Kutcher, told her, "I don't think you're going to be good at [acting]." Jones, who gave birth a son last year, is currently single, as is Kutcher, but we suspect she's not interested in a reconciliation.
