Long hours on set for months on end, screen smooches and steamy sex scenes... it's not surprising so many on-screen romances spark off-camera chemistry. What is perhaps more surprising is when those intense passionate affairs turn into steady long-term relationships involving marriage and children (how frightfully un-Hollywood). Particularly given that most of the parties involved go on to put themselves in similarly intense situations with similarly hot co-stars.
These A-list couples fell in love on-set and turned their on-screen love story into a real-life happy-ever-after (at time of going to press). Which couples do you think will last the distance?
