Carey, who recorded with ODB in the 1990s, was one of the few allowed inside the VIP section Thursday at the Christian Cultural Center in Brooklyn, where the red-cherry wood coffin was surrounded by a red velvet rope, the New York Post reported Friday.
Members of the Wu-Tang Clan, which ODB co-founded, and Kurtis Blow, one of rap's first commercially successful artists, also attended the service.
ODB, whose real name was Russell Tyrone Jones, died suddenly Saturday at a New York recording studio, just two days before his 36th birthday.
Cause of death remains unknown, although he reportedly complained of chest pains and shortness of breath prior to his death.
