6 Actors Who Broke Up BEFORE Their Movie Was Released

6. Robert Pattinson And Kristin Stewart - Twilight Saga: Breaking Dawn Part 2

The affair that was so widely reported that even a certain ex-President commented on it, Robert Pattinson and Kristen Stewart's break up in 2012 was messy and very, very public.

Us Weekly broke the news that Stewart had been photographed with Robert Sanders, who was directing her in Snow White and the Huntsman at the time. He was already married, while Stewart was in a high publicised relationship with her Twilight co-star Pattinson. The pair had begun a romance after completion of the first Twilight film, although they played down the rumours for some time.

The revelations came as the pair were yet to complete work on The Twilight Saga: Breaking Dawn Part 2. Stewart issued a public apology for her actions and their relationship ended. Needless to say their split did not hurt the Twilight franchise's box office earnings.

Stewart and Pattinson did briefly rekindle their romance in October of 2012 (this earning the ire of a Tweet-happy future politician). However, they separated for good in May 2013.
