‘Dancing with the Stars’ judges Bruno Tonioli and Carrie Ann Inaba have signed on to appear on ‘Dance X,’ a singing danceoff set for a January ABC debut.

According to the network: ‘Dance X’ will ’seek out the best dancers, whose rhythm will be tested on everything from breakdancing to disco, would-be contest winners must also be able to carry a tune, with the show’s end game focused on building a viable song-and-dance troupe.’
