SHARON Osbourne has quit 'America's Got Talent' because of NBC's "discrimination" against her son Jack.
The showbiz matriarch was furious when 26-year-old Jack was axed by email from reality show 'Stars Earn Stripes', allegedly because of his multiple sclerosis (MS) diagnosis, and has now decided she no longer wants to work for the network.
She told the New York Post newspaper: "I just can't be fake. It's discrimination and it was badly handled. It's time to move on."
Sharon remains under contract to NBC but she isn't worried about any possible ramifications.
She added: "All they can do is stop me from being a judge on another network for five years."
Last month, 'Stars Earn Stripes' producer David Hurwitz claimed Jack was never hired for the tough reality contest.
He said: "He was somebody we were in talks with."
Both Sharon and Jack - who was first contacted about the show in April - admit a contract was never signed but insist the deal was moving forward on a verbal commitment.
After he agreed to take part, the 'Adrenalin Junkie' host - who went public with his debilitating medical condition in June - received an email on May 18 from Chuck LaBella, the network's vice president of talent relations, confirming his participation.
However, soon after disclosing his condition, Sharon says she received an email from NBC, which read: "We cannot move forward with Jack's participation".
She also claims NBC offered to pay Jack - who said he would fund his own insurance policy - his full appearance fee but they declined.
A representative for NBC said they regretted any "misunderstanding" which has led to Sharon leaving 'America's Got Talent'.
The representative said: "Sharon has been a valuable part of the NBC family. We regret any misunderstanding and wish Jack well."
