Hollywood really is like a big small town, isn't it? 'Mad Men' star January Jones sat down with GQ and did some serious dishing (which is the best kind, right?). Like: January used to date Ashton Kutcher.

[Ashton] was "not supportive" of her acting career, she says. "He was like, I don't think you're going to be good at this."

But that was for the best.

"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."

I bet Jack Nicholson would beg to differ. January knows him from when they worked together in the 2003 film 'Anger Management,' and she said Jack watched nearly the entire first season of 'Mad Men' without realizing his old co-star was Betty Draper! Now that's truly becoming a character :)

In all fairness, though, January did stress to GQ that she's nothing like her character, Betty.

Would you have paired January with Ashton?
