21 Couples Who Had to Work Together After Their Real-Life Relationships Ended

Vartan and Garner first met on the set of "Alias" in 2001, though they didn't start dating until two years later. Their relationship only lasted until 2004, and the two both remained on the show — playing lovers Michael and Sydney — until its finale in 2006.

In 2005, Vartan told USA Today that their breakup was "benign" and that he and Garner decided they were "better off as friends." They were so close that Garner even told Vartan about her engagement to now ex-husband Ben Affleck before the rest of the world found out. "On the surface, it could have been a recipe for disaster," Vartan said of their on-set relationship following their breakup. "But Jennifer and I were best friends first, during, and after."
