15 Couples Whose Real-Life Romance Ruined Their Show

by at .

It happens pretty often. Actors meet while working together on a show, and the next thing you know, they hit it off.

These 15 couples dated while working on their shows, sometimes playing a couple on the show while also dating in real life. Or, in some cases, they played siblings.

Either way, those relationships (and the subsequent break-ups) definitely had an affect on their shows.

Here are 15 couples whose real-life romances ruined their shows.

1. Nina Dobrev and Ian Somerhalder
