Actor Jake Gyllenhaal is flattered by rumours he is bi-sexual, even though he insists he is only attracted to women.

Gyllenhaal, who plays a homosexual cowboy in new movie Brokeback Mountain alongside Heath Ledger, has never had a gay experience - but he isn't afraid of the possibility of having a sexual relationship with another man.

He says, "You know it's flattering when there's a rumour that says I'm bisexual. It means I can play more kinds of roles.

"I'm open to whatever people want to call me. I've never really been attracted to men sexually, but I don't think I would be afraid of it if it happened."
