The 30-year-old, who met her boyfriend of five years Hayden Christensen on the sets of 2007 movie "Jumper", said finding a partner through work is a normal thing, reported Contactmusic.
"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?" Bilson said.
The actress, who also dated her 'O.C.' co-star Adam Brody for three years before they split in 2006, said she doesn't play by the rules when she is in a relationship and prefers to rely on her instincts when judging a man.
"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," she added. PTI AYM
