So it seems Omarion has signed on to be a judge on MTV's hit show, 'America's Best Dance Crew.' Omarion will join JC Chasez and Lil Mama as the third judge on the show's upcoming fifth season, beginning at the end of January. He will replace hip-hop choreographer Shane Sparks, who lost his spot on 'ABDC' when he was arrested in December and charged with several counts of child molestation. Season Five of 'America's Best Dance Crew' premieres Jan. 28, at 10PM on MTV. Omarion's third studio album, 'Ollusion,' hit stores on Jan. 12. Check out the best crew to hit the stage on ABDC in many people's opinion, The Jabbawockeez.
