From this season, until her departure in 2002, Whoopi Goldberg would no longer be designated as a secret square. This may be due to players choosing her as the first pick of a round quite frequently.
Featured stars: Betty White, Alfred Molina, Sharon Lawrence, Bruce Vilanch, Caroline Rhea, Gilbert Gottfried, Greg Gumbel & Phil Simms, Brad Garrett, and Whoopi Goldberg
