Cheech and Xena sing on new Fox show

NEW YORK (AP) -- Cheech Marin and Lucy Lawless will be among the contestants trying to prove they can carry a tune on Fox's "Celebrity Duets."

The weekly singing competition, which debuts August 29 (8 p.m. EDT), will match eight competitors of where-are-they-now? celebrity with a different professional singer/duet partner each week, Fox announced Tuesday.

Rounding out the roster of celeb-singers are Alfonso Ribeiro, Jai Rodriguez, Hal Sparks, Lea Thompson, 2004 Olympic gold medal-winning gymnast Carly Patterson and wrestling champion Chris Jericho.

Wayne Brady will host the show, with producer David Foster serving as a judge.

"Celebrity Duets" will move to its regular time slot on Sept. 7 (9 p.m. EDT).
