Jack Osbourne Fires Back at NBC

He was let go from NBC’s “Stars Earn Stripes” suspiciously close to when he announced his Multiple Sclerosis diagnosis, and Jack Osbourne is upset about the whole ordeal.

The 26-year-old television personality, whose mother Sharon quit “America’s Got Talent” over the incident, took to his Twitter account to express his anger.

“NBC said they didn’t fire me over my diagnosis? Bull-F**king-S**t,” he tweeted, along with a link to an NBC press release claiming that Osbourne’s illness wasn’t to blame.

Jack continued, "I took part in a 16 hour challenge over 30 miles with a 40 pound ruck [sack] on my back in January. I had MS then. Don't tell me [what] physically demanding is."
