Anna Faris Admits To Stalking An Ex (VIDEO)

Anna Faris got up close and personal on all the late night talk shows this week -- admitting, among other things, that she used to be a creepy stalker.

Last night she was on the Late Night with Jimmy Fallon show to talk about her latest movie, 'What's Your Number?' when the conversation turned to her past relationships.

In college, Faris was dating the love of her life (he had even given her a promise ring!) when she suddenly found herself dumped and listening to Pink Floyd's 'Wish You Were Here' on repeat. "I would cry," laughs the actress. "And then I would watch myself in the mirror cry. And I would feel really sorry for myself."

But being a woman of action, Faris eventually decided to take things into her own hands and change his mind. Here's what she did to try to win him back: "I stalked him for a while. I paged him all the time. I knew his whole class schedule. I would show up at his fraternity at like one in the morning."

After college, Faris continued to be a little bit unlucky in love before finding "The One." She divorced her first husband Ben Indra in 2007 after three years of marriage, but found happiness when she married fellow actor Chris Pratt in 2009.

We're guessing Faris no longer has to stalk guys to get their attention -- and we'd also bet that her college sweetheart is kicking himself right now for letting her go!
