*Boxing champ Roy Jones Jr., singer Mya and singer/percussionist Sheila E. are among the celebrities who will compete in the upcoming CBS reality series, "Secret Talents of the Stars."        

       Premiering live on April 8 at 10 p.m., the show will feature actors, athletes and music artists who will compete against each other by performing an unknown talent. Like "American Idol," judges will critique the performances, but viewer votes will decide who goes home each week.      

       Roy Jones Jr. will compete as a rapper, while Mya attempts to earn victory as a tap dancer. Also, former "Cosby Show" star Malcolm-Jamal Warner will perform bass guitar on an original song, Sheila E. will juggle with The Flying Karamazov Brothers and former boxing champ Joe Frazier will compete as an R&B singer.

       Other celebrities slated to appear on the seven-week show include actress/model Marla Maples, Olympic medalist, Sasha Cohen, spokesmodel/actress Cindy Margolis, actor/radio DJ Danny Bonaduce, model/actress Bridget Marquardt and pop culture personality Ben Stein.
