Celebrity Fit Club

The 5th season cast includes:

Maureen McCormick (Marsha, Marsha, Marsha...ie Marsha Brady)
Dustin Diamond (from Saved by the Bell and his self-released sex tape)
Tiffany (former pop star..."I think we're alone now")
Cledus T. Judd (country music guy)
Da Brat (chick rapper)
Ross 'The Intern' Mathews from The Tonight Show (who?)
Kimberley Locke (American Idol contestant)
Warren G (the rapper)

Even though I am pretty sure VH1 should change the name to D-List Celebrity Fit Club, I'm still going to watch in April when it premieres.
