Celebs you think are gay or bi but everyone believes to be straight?

Ewan McGregor (Youthful experimentation, he's definitely sucked a cock once.)
Colin Farrell, although I'd probably say he's pan.
Sir Patrick Stewart (Again, youthful dalliances during his theatre days, him and Ian McKellen totally fucked when they were in a play together and were pissed one night back in the day.)
