Singer's mother to assume management.
Sources say Brandy has severed ties with manager Benny Medina of Handprint Entertainment.
The news comes before the June 29 release of her Atlantic album, "Afrodisiac."
Sonja Norwood, Brandy's mother, is assuming full management responsibility through her company, Norwood & Norwood.
Medina, whose client roster includes Mariah Carey, made headlines last year when high-profile client Jennifer Lopez terminated their management agreement.
