Muppets meet mistletoe

Stars come out for holiday special

"Sesame Street" is going primetime with a star-studded holiday special for ABC.

Ben Stiller, Jamie Foxx, Jennifer Hudson, "The Sopranos'" Tony Sirico and Steve Schirripa, singers Alicia Keys, Sheryl Crow and Brad Paisley and Ty Pennington of ABC's "Extreme Makeover: Home Edition" have signed on for "Elmo's Christmas Countdown." The one-hour special, which will feature the celebrities helping host Elmo count down the days leading up to Chirstmas, is filming to air during the holiday season.

Stiller will voice Stiller the Elf, a muppet modeled after the comedy star that will serve as the special's narrator.

Sirico and Shirripa will shed their tough-guy image from their years on "Sopranos" in a skit in which they will play Bert and Ernie with guidance from the real Muppets.

Foxx, Hudson, Keys, Crow, Paisley and Pennington will appear as themselves to perform musical numbers.

"Countdown," from Sesame Workshop, will also co-star "Sesame" characters Big Bird, Grover, Oscar, Count von Count and Snuffleupagus.
