VH1's "Celebrity Fit Club" is returning for a brand new weight losing fifth season in April, with this edition featuring Dustin Diamond, Da Brat and others.

The cast of "Celebrity Fit Club 5" is the fittest bunch yet, said VH1, giving drill sergeant Harvey Walden IV the chance to push the contestants even further.

This season's cast includes "The Brady Bunch's" Maureen McCormick, Dustin Diamond from "Saved By The Bell," pop star Tiffany, country music artist Cledus T. Judd, rapper Da Brat, Ross "The Intern" Mathews from "The Tonight Show,""American Idol" contestant Kimberley Locke and rapper Warren G.

The program features Walden as well as nutritional & diet expert, Dr. Ian Smith and host ANT. But this season also brings in a new psychotherapist, Stacy Kaiser.
