Daughterqueen, I think what might surprise you is that all the Michael Ball fans I know - and I know a LOT because I've been a fan for over 20 years - are already completely aware of his sexuality. And, do you know what? We really don't care!
Michael has said basically that "he's said enough to make people aware but he doesn't think being specific about it is anyone's business". (Or words to that effect.)
John Barrowman has chosen to be open about his sexuality and that's his own choice, good for him. Michael prefers to keep quiet and that's his choice too.
Michael's a fabulous entertainer, as is John Barrowman. We fans don't give a hoot about their sexuality, those days are long gone thank goodness!
