LeAnn Rimes joins regulars Robin Thicke, Jenny McCarthy, Nicole Scherzinger and Ken Jeong on the panel for the Season 5 finale of this zany but heavily watched game show hosted by Nick Cannon, who appeared as one of the masked celebrities himself earlier this season. It'll be an interesting change of perspective for Rimes, who won Season 4 last fall disguised as the Sun. Previously unmasked celebrities this season have included Tyrese Gibson, Tamera Mowry-Housley, Bobby Brown, Mark McGrath and Caitlyn Jenner.
