While Ray J has proven himself in projects not involving Brandy, the natural chemistry between the performer and his big sister has been showcased in several projects pairing the two. Ray J began appearing on his sister's series "Moesha" (UPN) in 1996, first playing a recurring character named Charles. In 1997 he was featured on the series as himself in an episode that had Brandy doing double duty, appearing both as herself and her TV alter ego. Beginning in 1999, he took a regular role on the show, playing Dorian, the titular girl-next-door's troubled cousin. His character brought more hard-hitting storylines to the previously sugar-coated series, and was eventually revealed to actually be Moesha's half-brother, the two sharing Frank Mitchell (William Allen Young) as their father.
