Chad Michael Murray & Sophia Bush – One Tree Hill
All was great between these two love birds when they first met on set and married a year later. Unfortunately, things went south, and they divorced five months after that with Bush alleging that Murray had cheated on her. Of course, the problem was that the two had to continue filming together for another three years, which must have been excruciating. Disliking someone you work with is bad enough, but how much worse when you were married to them?! Looking at Bush’s face above, she certainly looks less than thrilled.
