As Season 5 of Fox’s “The Masked Singer” heads toward its conclusion at the end of the month, Variety has the scoop on the guest panelists and show formats for the final three episodes.

On Wednesday, the “Spicy 6” episode saw actor/singer Tyrese Gibson unmasked as the Robopine. When “The Masked Singer” returns next week on May 12, the quarter finals will feature comedian Rob Riggle (“Holey Moley”) as a guest panelist, alongside regular panelists Nicole Scherzinger, Ken Jeong, Jenny McCarthy Wahlberg and Robin Thicke.

The following week, on May 19, the semi-finals will feature guest panelist Darius Rucker — that’s right, the Hootie and the Blowfish singer will join in on the guessing game. Also in that episode, the show’s mysterious “Cluedle-Doo” will be revealed.

New this season is the masked celebrity “Cluedle-Doo,” who has been offering additional hints about each contestant. Last week was the first reveal toward Cluedle-Doo’s identity: “I have a connection to another mischievious Masked Singer from the past: The Gremlin.” (That was Mickey Rourke, unmasked in Season 4.)

Finally, that all leads to the show’s Season 5 finale on May 26. Joining the panelists will be guest LeAnn Rimes, who won Season 4 last fall as the Sun.

Gibson as Robopine joined previously unmasked celebrities Bobby Brown (Crab), Tamera Mowry (Seashell), Mark McGrath (Orca), Nick Cannon (Bulldog), Logan Paul (Grandpa Monster), Danny Trejo (as Raccoon), Caitlyn Jenner (as Phoenix) and Kermit the Frog (as Snail).

The Season 5 contestants boast a combined 26 Grammy nominations, nine multi-platinum singles, four Academy Award nominations, three Super Bowl appearances, six gold medals and two world records. Guest panelists this season have included Joel McHale, Rita Wilson and Chrissy Metz.
