Hollywood's best actors and actresses spend tons of time rehearsing their lines together during months of production. Sure, they are professionals, but sometimes, it's hard to deny natural attraction after hours and hours of working together.
These stars, however, took their on-screen romances to the next level. While some co-star couples, like Blake Lively and Ryan Reynolds, have withstood the test of time, dozens of other on-set couples have failed. Here are ten co-stars who fell in love on set, but didn't last.
10 Megan Fox & Shia LaBeouf

Their on-screen chemistry was so strong it landed them a Teen Choice Awards nomination for Choice Movie: Liplock. Although Fox admitted, in an interview on Watch What Happens Live with Andy Cohen, she did having feelings for LaBeouf and "loved him," their romance didn't last further than their time on the movie.
