Working on a movie set with someone every day for three months, having to act out intense chemistry, and practicing lots of choreographed sexy-time moves is a formula for real-life romance. It sure worked magically for awkward beauty Kristen Stewart and Robert Pattinson, who star as a melodramatic, star-crossed couple in the blockbuster Twilight series. The final installment, Twilight: Breaking Dawn, Part 2, hits theaters this week, and it's a good thing, too, because Pattinson and Stewart have been on the outs. In case you've been dead to the world, tabloids recently exposed Stewart's fling with director Rupert Sanders. It was a giant uh-oh for Twilight fans, but perhaps indicative of what happens when you turn your co-worker into your bed slave.

Pattinson and Stewart, a.k.a. Robsten, are only one of many couples that tool their business from fake bedrooms to real ones, so we did some research to find out how these things usually go. Some worked out, some failed miserably. It's all ahead, as Complex revisits 25 Movie Couples Who Dated In Real Life.
