Why all the sexual orientation questions?
In lots of interviews he mentions girlfriends or ex-girlfriends.
In one interview he talks about a non-actress girlfriend he dated on and off for years and even jokes about how he "stalked" her/left things on her doorstep.
It seems pretty clear that he is straight. though perhaps he is bi-sexual, however he is certainly likes chicks. if he likes dudes too, more power to him.
Just wanted to clear that up....
