Rachel Bilson insists it is normal for actors to date their co-stars - after she fell in love with Hayden Christensen on the set of JUMPER.
The former O.C. star met the actor while they were making the 2008 action movie and they soon started dating.
Bilson was also romantically involved with Adam Brody while they were both starring in the teen drama series. They split in 2006.
And the actress is convinced that if you work with someone everyday, it is easy to fall for their charms.
She tells New York Post magazine PageSix, "They say don't date your co-star, but that’s who you're around. If you're in an office, and you see someone everyday and you click well, you'll start dating. It’s the same thing."
And she adds of Christensen, "I have someone really great. Someone who can make me laugh - that’s always what comes first. It’s the best to be able to really, like, truly laugh with someone like they're your best friend, you know?
