Being an on-screen couple can draw actors closer to together, but in some cases it flourishes into full-blown love. Ever wondered why you can feel the simmering lust between some movie couples? Well, it's often because there's something going on behind the scenes!
Here are 10 movies featuring couples who were also lovers in real life (and some have stood the test of time!)
1. Gigli in 2003, with Jennifer Lopez and Ben Affleck
Lopez played Ricki, a man-hating serial killer who suddenly falls for the charismatic Larry (Ben Affleck). This amorous encounter enables Ricki to change her opinion of men and of life in general. Lopez and Affleck weren't in relationship before this crime/romance was filmed, but as the shoot when on, they fell in love. Although their relationship didn't last, for a while 'Bennifer' was the hottest celebrity couple on the Hollywood circuit!
2. Vicky Cristina Barcelona in 2008 with Penelope Cruz and Javier Bardem
These Spanish actors got together during filming and it was clear from Javier's performance that he was smitten with gorgeous Penelope. And it's proved to be a lasting liaison - now married and parents to 2 children, they're still head over heels in love and are frequently seen cozying up to each other.
3. Cruel Intentions in 1999 with Reese Witherspoon and Ryan Phillippe
Another couple who went on to tie the knot and have a family. Although they have since separated, they remain friends and Ryan has frequently credited Reese for mothering skills.

Monica Bellucci was relatively unknown when she landed her role and managed to seduce French heart-throb Vincent Cassel whilst shooting The Apartment. Cassel was already famous for his womanizing ways, but he fell for his stunning Italian co-star and their relationship lasted for several years.
5. The Rum Diary in 2010 with Amber Heard and Johnny Depp
Depp's personal life was thrown into turmoil after filming this movie. He left French superstar Vanessa Paradis, the mother of his children, and set up home with Amber Heard.

Sadly this relationship has turned into an acrimonious divorce, so who knows what the future holds for our favorite swashbuckling pirate?
6. Step Up in 2006 with Jenna Dewan and Channing Tatum
Love mixed with dance has always attracted audiences, but this movie was no Dirty Dancing as Dewan and Tatum continued their passionate moves off-set.
