B2K lead vocalist Omarion (born Omari Ismael Grandberry) went solo in 2005 with O, featuring production help from the Neptunes, Rodney Jerkins, and the Underdogs. The title track, released as the lead single, helped send the album to the top of the Billboard 200 chart. His second album, 21, followed in late 2006 and was kicked off by an excellent Timbaland production, the Top 20 single "Ice Box." His next move was Face Off, a full-length collaboration with Bow Wow released in December 2007. Following a split with Sony BMG, he signed with EMI, where he released 2010's Ollusion. Also an actor, Omarion appeared in the movie version of Fat Albert, as well as You Got Served, The Bernie Mac Show, Cuts, and Feel the Noise.
