Backstreeters, Ulrich, McGrath Set For Celebrity 'Millionaire'

Sisqó, Gene Simmons, Dixie Chick also set for charity shows airing February 11 and 14.

Backstreet Boys Nick Carter and Howie Dorough, Metallica's Lars Ulrich, Sugar Ray's Mark McGrath and Sisqó are among several musicians who will be faced with a difficult question next month: Is that your final answer?

In an attempt to beef up its already top-rated show, ABC announced Friday it will air a special celebrity edition of "Who Wants to Be a Millionaire" that features music stars competing against one another for charity.

Kiss' Gene Simmons and the Dixie Chicks' Emily Robison will also compete on the show, which in the past has included Puff Daddy, 'NSYNC's Lance Bass and Vanessa Williams in celebrity editions.

The special episodes of "Who Wants to Be a Millionaire" will tape on February 1 and air February 11 and February 14, according to ABC. As always, Regis Philbin will host the show, and competitors who reach the hot seat will receive three lifelines. All of the stars are guaranteed $32,000, which they will donate to a charity of their choice.

McGrath, who is working on the next Sugar Ray album, is an experienced game show participant, having smothered musicians such as the Eagles' Joe Walsh and Mötley Crüe's Vince Neil on celebrity editions of VH1's "Rock & Roll Jeopardy!"
