Aunt Leolah Brown launched into an angry tirade and had to be ejected from the funeral service. The sister of Bobbi Brown attacked Pat Houston, calling her a "phoney", according to a Sun on Sunday report. Pat Houston is the sister-in-law and former manager for the late Whitney Houston.

Singer Dione Warwick also joined in the argument saying the funeral's Sweet 16 prom theme was "disrespectful".

The body of Brown, 22, was carried in a silver casket to St James United Methodist Church in Alpharetta, where the invitation-only service included grandmother Cissy Houston; Bobby Brown and his wife, Alicia; and celebrities including media mogul Tyler Perry and singer Monica.

Police are expected to question Bobbi Kristina's boyfriend Nick Gordon. He was told to keep away from the funeral service.
