London: Scottish actor Gerard Butler, who is looking for lasting love these days, says he is determined not to fall in love with movie co-stars after his previous on-set dalliances ended in "disaster".

Butler, 42, who has been linked to a string of Hollywood beauties including his 'The Bounty Hunter' co-star Jennifer Aniston and Cameron Diaz, admits it is too easy to become infatuated with an actress while at work, as reported.

"That's a dangerous path. When you're making a film with someone, you get to know them very well indeed and it's too easy to develop a sort of obsession with them that you think at the time might be love. But it isn't.

"Earlier in my career, I had a couple of relationships with co-stars and both times it was a disaster," he said.
