It’s been reported today that Jack Osbourne – who is of course the son of TV personality Sharon Osbourne and rock star Ozzy – has been ditched by a US TV network after they learned that he’d been diagnosed with Multiple Sclerosis.

Jack made the shocking revelation while appearing on The Talk, an American chat show that features Sharon on the celebrity panel.

He explained, “I had booked a job, right when I got diagnosed, and the company didn’t think I could actually perform the job.

“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.”

Sharon caustically added, “It was a really nice email…”

The Sun revealed that it was NBC’s Stars Earn Stripes, in which soldiers put celebs through real military exercises, who bailed on Jack.

The paper adds, “A show source admitted they didn’t think Jack was up to the challenges — but said it was hard to believe he was informed by email.”

However, while Jack has thanked fans for their messages of support now he’s gone public with his illness, it seems his patience with the media is in short supply after he tweeted, “Dear journalists…will you please stop sensationalizing my situation to sell ur poorly written magazines and papers. I AM NOT DYING!” [sic]

And likewise, when he walked onto the set of The Talk, holding Sharon’s hand, he was said to be “overwhelmed” by the cheers and chanting from the audience.

Jack asked everyone to stop, saying, “I’m not going to cry! Stop, stop!”

Here’s a clip from his appearance…
