Sharon Osbourne has accused NBC of “discrimination” against her son Jack, prompting her to quit the show, America’s Got Talent.

Sharon was said to be furious when 26-year-old Jack was axed by email from the 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, “I just can’t be fake. It’s discrimination and it was badly handled. It’s time to move on.”

A representative for NBC said they regretted any “misunderstanding” which has led to Sharon leaving America’s Got Talent.

“Sharon has been a valuable part of the NBC family. We regret any misunderstanding and wish Jack well.”

Just a few days ago, Sharon addressed rumors that she hadn’t been asked to return to the show.
