According to the 48-year-old, whose hit films include Reality Bites and The Truth About Cats & Dogs, she and Cohen "got married drunk in Vegas…We dated for a year, and we got married at a drive-through chapel in a cab."

"[We thought] you have to go down to the courthouse and sign papers and stuff, so who knew?" she quipped. "We were married, and apparently now that [Rob] is getting married for real, his lawyer dug up something."

Cohen is now engaged to Jill Leiderman, a producer on Jimmy Kimmel Live.

All's well that ends well!
