In Hollywood, since you spend so much time with your fellow cast members, it is normal to date them. That is what happened to Jennifer Morrison and Jesse Spencer, who met on the set of House M.D. and got engaged during the Christmas holiday season in Paris at the top of the Eiffel Tower.

This beautiful actress is now single again after they called off their engagement. To make things work for the couple, they will have to work together on the show. Talk about moving on after breakup!
