As for dish--this isn't great, but apparently Nicole Kidman was being interviewed by an American journalist and mentioned that Robbie Williams is gay. Noticing that the journalist's jaw was on the floor, she gave him quizzical look and said that he's pretty much out to most of his friends and that she didn't think it was a big secret. She may've been playing, I don't know. Sorry, I can't cite a reference, but I've heard this more than once from different sources.
He is cute, definitely has the hot bloke vibe.
