Sharon Osbourne has quit her role as a judge on "America's Got Talent" for allegedly discriminating against her son for having multiple sclerosis.
NBC emailed Jack Osbourne only two days before shooting began on an upcoming reality series "Stars Earn Stripes", which puts celebrities through military training including "dangerous water stunts, strenuous physical activity, and uses live ammunition."
Sharon says the channel discriminated against Jack because of his illness, despite doctors saying he would be perfectly capable of competing against other celebrities on the show.
Speaking in June, Jack said the email from NBC angered him more than finding he has MS:
"I had booked a job, right when I got diagnosed, and the company didn't think I could actually perform the job," he said on the show. "Out of everything, that's what has really ticked me off the most because it's like, 'Don't tell me what I can and cannot do'.
"At no point did they call me. It was all through agents and lawyers I was offended by it."
NBC chairman Bob Greenblatt denies the accusation, and says NBC doesn't discriminate on any basis. "We have the deepest affection for Sharon Osbourne and consider her to be part of the NBC family, and our hearts go out to her, Ozzy, Jack and his family at this time."
