Oh, you mean like, closeted celebrities?
There's already a thread like that, but I'll indulge your question.
Patrick Swayze. I always got a swinger vibe from him.
Brandon Routh. That's prolly why he played gay in "Zack an Miri."
George Clooney. If not a self-loathing gay, then a total douchesack.
Justin Long. He seems "open" to try new things
Bam Margera. I dunno why, but I always trust my gaydar.
Dane Cook/ Nick Swardson. I don't know if he's ever stated otherwise, but Nick totally gives off a gay vibe. Dane--well, he gives off the same vibe, but maybe that's because he's a joke jacker.
Will Smith, John Travolta and Tom Cruise. Just because someone has kids the old fashion way doesn't make them any less gay.
