Dating co-workers is a tricky business in general, but when two celebrities date one another, a break-up can be extra brutal if the two work together.

Several celebrities have met on movie or television show sets over the years, and while some have found true and everlasting love, most others have eventually called it quits on their romances. These couples, unfortunately, have sometimes been forced to put any bad blood they may have had between them aside however, as they continued to work together -- and sometimes, even date-on-screen.

While this situation has happened with movie co-stars (Kristen Stewart and Robert Pattinson come to mind), it is most often something which occurs on the sets of popular television shows, where stars who date may be forced to work together for years on end, as their shows continue to grab the attention of their audience.

Making matters even worse for some of these couples, they are also forced to be romantically involved with their ex on-screen, adding to the potential drama that can occasionally pervade their sets.

Enstars compiled a list of eight celebrity couples who met on the set of a television show, dated, and then were forced to continue working together-either happily or unhappily-after they broke up.
