Leolah Brown has reportedly left the funeral service of her niece Bobbi Kristina Brown after venting anger at the role of another relative, Pat Houston.
The outburst reflects the continuing tensions in Bobbi Kristina Brown’s family even after her death.
Bobbi Kristina Brown, 22, died at a hospice on July 26, six months after she was found face down and unresponsive in a bathtub.
She is expected to be buried beside her mother at a cemetery in New Jersey on August 3.
Speaking to media outside the church Bobbi Kristina’s aunt and Bobby Brown’s sister said the funeral was going “wonderfully” well until Pat Houston started speaking.
“I didn’t like that, so I left… I just told her that Whitney is going to haunt her from the grave.”
Pat Houston is Whitney Houston’s sister-in-law and former manager.
“It’s just getting started,” she said.
The funeral service at St James United Methodist Church in Alpharetta, which was closed to the public, lasted about two hours and has now ended.
Those attending Bobbi Kristina Brown’s funeral service included father Bobby Brown; grandmother Cissy Houston; cousin Jerod Brown; Atlanta mayor Kasim Reed and R&B singer Monica.
An initial autopsy found no obvious underlying cause for Bobbi Kristina Brown’s death. She was discovered in the bathtub at the Atlanta home she shared with her partner Nick Gordon in January.
Bobbi Kristina Brown’s mother, pop icon Whitney Houston, drowned in a bathtub at a Los Angeles hotel in February 2012 on the eve of the Grammy Awards ceremony.
