'America's Got Talent': Sharon Osbourne Left Due To Mistreatment Of Jack Osbourne

Sharon Osbourne has finally revealed the reason behind her abrupt "America's Got Talent" departure.

According to The New York Post, the former "AGT" judge left the series due to NBC's decision to cut ties with her son Jack after he was diagnosed with multiple sclerosis.

“I just can’t be fake,” she explained. “It’s discrimination, and it was badly handled."

Osbourne also provided the Post with an email she received from NBC that read, “We cannot move forward with Jack’s participation."

Osbourne announced she wouldn't be returning for Season 7 of the NBC show in June, and made sure to clear up any rumors that her departure had to do with how much she was being paid.

"Money is not the reason I'm not returning," Osbourne tweeted in July. "It's because ..." and left it at that.
