The reality show is back for its sixth season, hosted by Tom Bergeron and featuring judges Len Goodman, Carrie Ann Inaba, and Bruno Tonioli. Twelve celebrities, evenly split between males and females, compete against each other to be the best dancer. Among them are actors Steve Guttenberg and Marlee Matlin, professional tennis player Monica Seles, and Olympic figure skater Kristi Yamaguchi. Helping them reach their goal are 12 professional dancers, most of them returning from previous seasons but with the addition of 2006 Mambo World Champion Fabian Sanchez. In the middle of the season is the show's 100th episode, where more than 30 former cast members and pros return for live performances and interviews.
