Dustin Diamond, who may forever be known to the world as Saved by the Bell’s geeky Screech, has allegedly upset his fellow contestants on Celebrity Fit Club. He’s been ‘quarantined’ from the rest of the cast and crew. That means he won’t be weighing in with them during the show or taking part in the challenges. Apparently Diamond will not be allowed to have any contact with the cast for the remainder of the shoot.

What happened?

According to PerezHilton.com, Screech got into a verbal altercation with former American Idol singer, Kimberley Locke. He screamed some obscenities at her. This caused Locke, 80s pop singer, Tiffany, rapper Warren G, and The Brady Bunch’s Maureen McCormick (Marcia), to storm off the set.

A rep for Mr. Diamond has denied all allegations against the former child star.

In other Fit Club news, host Ant and diet expert, Dr. Ian Smith, also got into it. Reportedly, Dr. Ian was upset when Ant lit up a cigarette near him. He began to shout and threaten Ant with physical action if he didn’t put it out immediately.

Who says diets don’t make people cranky?
