That's not bisexuality, that's acting. Unless these guys are method actors and go out on the pull to get into the feel of things. ;]

As it is, I think they like to leave it ambiguous anyway. It's better for the glossies, and the glossies keep their careers alive or dead. If the glossies decide that they're straight, they ignore them. If the glossies find out that they're gay, they mock them. If the glossies don't know anything but suspect a lot, all you get is a continuous cycle of rumours, and it does good things for both the magazine's long-term, and the actor's name-recognition.
