Rachel Bilson, known for her role in Waiting For Forever, feels it's natural for actors to date their co-stars.
She too met her boyfriend of five years Hayden Christensen on the set of 2007 movie Jumper, reports contactmusic.com.
She said: "Dating co-stars is natural. When you're working with someone, it's habit. I met my man at work. I'm attracted to mysterious men. Every woman can relate to that, right?."
But Rachel, who also dated her O.C. co-star Adam Brody for three years before they split in 2006, admits she doesn't play by the rules when she is in a relationship.
"I've been in relationships where we've said, 'I love you' after two weeks. I think it depends on the person and the relationship. If it feels right, go with it. Love shouldn't play by the rules. It's all about chemistry."
