The ongoing tensions between the families of the late megastar Whitney Houston and her ex-husband, R&B singer Bobby Brown, have erupted during a memorial service for their daughter, Bobbi Kristina.

Bobbi Kristina, who dreamed of growing up to achieve fame like her mother, died in hospice care on July 26, about six months after she was found face down and unresponsive in a bathtub in her suburban Atlanta home.

A longstanding rift between families of the young woman’s famous mother and father broke out into the open at a service being held for Bobbi Kristina in Alpharetta.

Leolah Brown, the sister of Bobby Brown, walked out of the church and spoke to reporters gathered outside, telling them she was angry because Pat Houston was speaking at the funeral.

Pat Houston is the sister-in-law and former manager for the late Whitney Houston.

“I told her that Whitney is going to haunt her from the grave,” Leolah Brown said outside the church.

She suggested that the feud between the Houstons and the Browns was far from over.

“It’s just getting started,” she said.

Bobbi Kristina Brown was the only child of Houston and Brown and was raised in the shadow of her famous parents’ hugely public life.

She appeared alongside the couple in 2005 on the Bravo reality show Being Bobby Brown, which showed her parents fighting, swearing and making court appearances.

Bobbi Kristina was the sole heir of her mother’s estate. She identified herself on Twitter as “Daughter of Queen WH”, “Entertainer/Actress” with William Morris & Co, and “LAST of a dying breed”.

She told Oprah Winfrey shortly after her mother’s death in 2012 that she wanted to carry on Houston’s legacy by singing, acting and dancing, but her career never took off.
