From what I've been told by my friends in LA, who were the ones to tell me about George Clooney liking men :( Will Smith is definitely straight although his marriage is not a monogamous one, something his wife is completely happy about.
With regards to Tom and John Travolta, I've often suspected they're both Scientologists because the 'religion' promises to 'cure' homosexuality, I think Tom was introduced to it via his first wife Mimi.
The Hollywood not wanting to cast openly gay actors in lead roles is as old as Hollywood itself, just look at Rock Hudson and Montgomery Clift who spent their entire careers. Despite the power figures of Hollywood being made up of people with vastly varied sexual orientations, they've always had a very odd stance to homosexuality be it their leading men being opening gay or even characters on screen - in From Here to Eternity, Frank Sinatra's character trades sexual favours with men for cash, it's a big part of the book but is never even alluded to on screen.
Anyway I'm digressing..
Not really shocking about TomCat, am surprised they've lasted this long tbh. I guess all the money in the world wasn't enough for Katie Holmes. I think her film career never took off in the way promised to her. I wonder who he'll fall for next
