i've read that she had a crush on him in the nineties, and with some of those pics and the look in her eyes, i believe it. also..some of her songs seemed to chronicle her pursuit of him. and when he turned her down, a song seemed to chronicle that too. 'take a bow'. lol. i mean, the timing of the songs and the trip to the oscars was too suspect not to believe it. it started with a song called 'open your heart to me'..at least, i think that was the name of the song. plus..her song 'like a virgin' sounds so much like billie jean. lol. and while some of the stories of their possible attempt at a courtship were in tabloids..i know that after a story said that mj was non responsive, and wore sunglasses and she felt rejected and slapped them off of him...she did a rant on mtv's tenth anniversary, where she referred to Michael as 'Michael who?' and then...well..she deliberately made a rude body noise (use your imagination). it was clear that she was perturbed. again, the timing was quite suspect. madonna was always one with a shameless personality, and protocol was never her strongsuit, but it made her quite the fun person, in some ways..and disturbing in others, lol.
i know that at the elizabeth tribute, she kissed him. i believe they are good friends.
as for Britney, i know they are friends.
