Claire Danes
During the filming of Stage Beauty, Danes met and fell in love with actor Billy Crudup. Crudup had to leave his pregnant wife because the relationship had developed into something more serious. What a catastrophe. When Danes became closely engaged with her costar Hugh Dancy while on the set of Evening in 2006, she was found guilty of committing a second felony under California law. In this particular battle, Crudup was the last man remaining! Danes and Dancy were married in 2009, and their first child was born to them in 2013.
Melanie Griffith
During the filming of Two Much, this Hollywood power couple got to know each other. Both of them were married at the time, but they swiftly divorced their husbands after falling head over heels in love with each other. The couple married shortly after the divorce papers were finalized, and they went on to have one of the most stable relationships in Hollywood history. This is no longer the case because Griffith filed for divorce in 2016 after 20 years of marriage.
