Omarion got his start in the superstar R&B group B2K, and he's the only member to branch out into a successful solo career. Shortly after B2K's breakup he released his first solo LP O in 2005. Featuring production work from The Neptunes and Darkchild, it debuted at No. 1 on the Billboard 200 and earned him a GRAMMY® nomination for Best Contemporary R&B Album. He followed up with another No. 1 chart debut, 2006's 21, on which he co-wrote every song. Since then, Omarion has managed to segue into TV and movies, while still releasing records on Rick Ross's Maybach Music.
