We'll always remember singer, rapper, and actor Ray J's role on Moesha, and not just because he's actually Brandy's brother in real life! The triple threat starred in the sitcom from seasons five to six as Moesha and Myles' long lost half-brother, Dorian. The role transforms throughout the show, too: Dorian starts off as a supposed-cousin to the siblings, but it is later revealed that he is actually Frank's son from a secret affair. As he went on to gain notoriety for his singing career, his hilarious antics on the show are still pure gold.
