After a breakup, the last thing you will need is seeing your ex. Of course you need some time to process what happened, your emotions, and the thought of not being in a relationship with him anymore. But for these celebrities, there's just no time for that especially because they're working with their exes.
1. Jennifer Lawrence and Nicholas Hoult
Jen and Nick met on the set of X-Men: First Class in 2011 and hit it off. Things were going well, until they called it quits in January 2013 because of their busy schedules. They met again during the production of X-Men: Days of Future Past and rekindled their romance. However, they broke up again in 2014 and had to work together for X-Men: Apocalypse which hit theaters this year.
2. Nina Dobrev and Ian Somerhalder
Nina and Ian hit it off while they were working for the TV series The Vampire Diaries. Not only did they fall in love on screen as their characters Elena and Damon, but they also had great chemistry off screen as they were spotted spending their days off together. In 2013, however, the two announced their breakup and fans were devastated. They continued making TVD fans' hearts go kilig on the show, though, and even got the People's Choice Award for Favorite On-Screen Chemistry in 2014.
3. Blake Lively and Penn Badgley
Just like their Gossip Girl characters Serena and Dan, Blake and Penn started dating officially in 2008. They became everyone's fave couple because they were oozing with chemistry both on TV and IRL. But in 2010, two years before the series ended, the two broke up. They never rekindled their romance since then. Today, Blake is already married to actor Ryan Reynolds.
4. Kristen Stewart and Robert Pattinson
Twilight: Breaking Dawn Part 2 may have already finished filming when Kristen's cheating reports came out. However, she still had to work with her co-star and ex for the promotion of the franchise's last movie. The two have been on-and-off for quite some time, but they called it quits for good after.
5. Sophia Bush and Chad Michael Murray
Sophia and Chad met in 2003 when they started working on the TV series One Tree Hill. They eventually got engaged in 2005 but got divorced the following year. But they were still working together even after the split and tried to be professional with each other, even if Chad was dating another OTH actress even before his separation with Sophia was finalized. Ouch!
6. Rachel Bilson and Adam Brody
While working on the TV series The OC from 2003 to 2007, Rachel and Adam fell in love off screen, too, just like their characters on the show. But in 2006, the couple confirmed that they have broken up. Rachel is now with Star Wars actor Hayden Christensen, while Adam is now with Gossip Girl star Leighton Meester.
