He seems to me to be the kind of guy who would have no problem with being out and not caring what others thought of him.
I don’t think he’s gay. He does that predator thing a little to well. But he still pings my gaydar like mad every time.
Yep. Remember, he was a bigwig in the music industry for years before he became a tv star. Was he in the closet then? Or has he persuaded everyone who knew him to keep schtum?
Neither option seems likely.
Given that he’s completely in love with himself, might that not make him a little bit gay? 
The British thing is interesting to me. I guess I never noticed it before. I don’t think I ever noticed a British guy being more or less likely to be gay based on their British background. If that’s true, I may be way off.
Thanks, even sven for at least validating the “gaydar” feeling, even if it’s not true.
And no, I’ve never been to the Bally’s on Webster in Chicago. I find Simon’s shirts to be so un-heterosexual. I don’t expect the man to wear flannel, but his pec/nipple shirts are just skeevie to me. Then again, I don’t have pecs like that.
I know that this is off-topic, but I feel a brit should respond:
I don’t disagree that Brits may seem camp versus american stars on TV, but when you look at the developed world as a whole, it’s actually american men who seem atypical, who seem to have the biggest need to look macho.
C’mon peeps, it’s supposed to be the land of the free: wear a pink t-shirt, soften out that square haircut, drink a gin and tonic once in a while 
Not gay. As someone said upthread, he’s an asshole, not catty. Gay cutdowns have more of an edge than Cowell tends to have. He’s blunt, not sharp.
He’s not gay, he’s just really really vain.*
