"But when Prince was doing his Vegas residency around late 2006, Michael was living in Vegas. Will was a guest artist at the Prince residency, but he was also friends with Michael. So Will arranged it for Michael to be a guest in the audience at Prince's show. No one knew it really, but Prince knew it.
"There was a point during the show where Prince was playing bass and he came out into the audience with this giant bass—he knew where Michael was sitting—and he walked right up to Michael and started playing bass in Michael's face. Like aggressive slap bass."
"The next morning, Will went over to Michael's house for breakfast, and they're talking about Prince and the show. And then Michael goes, 'Will, why do you think Prince was playing bass in my face?'
"Michael was outraged. And then started going on. 'Prince has always been a meanie. He's just a big meanie. He's always been not nice to me. Everybody says Prince is this great legendary Renaissance man and I'm just a song-and-dance man, but I wrote "Billie Jean" and I wrote "We Are the World" and I'm a songwriter too.'"
