Anna Faris is busy promoting her latest comedic blockbuster, What's Your Number?, and stopped by Late Night to chat with Jimmy Fallon about her flick and shared some pretty hilarious off-screen love life stories.

"That 'Wish You Were Here' song was on repeat," she said. "I would cry and then I would watch myself in the mirror, cry, and I would feel really sorry for myself."

She added the split was extra hard because the dumper gave her a promise ring to which Jimmy quipped, "Was he a Jonas Brother?"

Anna also admitted to stalking her ex after being dumped.
