Whitney Houston’s daughter, Bobbi Kristina Brown, has been laid to rest amid new family drama.

Her father, Bobby Brown, emerged from the funeral service, staring toward the ground before lifting his head up and briefly gazing at the sky.

Dressed in all black, Bobby Brown was one of the first to exit the tension-filled private memorial service for Bobbi Kristina on August 1 at the St. James United Methodist Church in Alpharetta, Georgia.

Bobbi Kristina Brown, the only child of Whitney Houston and Bobby Brown, died in hospice care July 26, nearly six months after she was found face-down and unresponsive in a bathtub at her townhome on January 31.

Several celebrities showed up for the funeral including filmmaker Tyler Perry, Grammy-winning R&B singer Monica and Atlanta Mayor Kasim Reed.

In the middle of the service Bobby Brown’s sister Leolah Brown walked out of the church and spoke to reporters gathered outside. She said she was angry because Whitney Houston’s sister-in-law and former manager Pat Houston was speaking at the funeral.

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

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

“It’s just getting started,” she said before going back inside the church.

For years, there’s been a longstanding rift between the families of Bobbi Kristina Brown’s famous mother and father. Bobby Brown briefly appeared at Whitney Houston’s funeral three years ago, saying he and his children were seated but asked repeatedly to move. Bobby Brown said he left because he didn’t want to create a scene, but was upset.

Bobbi Kristina’s death was grimly similar to the way her mother had died three years earlier.

Whitney Houston’s assistant found the pop icon’s lifeless body face-down in a foot of water in her bathtub at the Beverly Hilton Hotel just before the Grammy Awards in 2012. Authorities found prescription drugs in the suite, and evidence of heart disease and cocaine in her body, but determined her death was an accidental drowning.

Her daughter, Bobbi Kristina, was found in the Atlanta home she shared with Nick Gordon, an orphan three years older, whom Whitney Houston had raised as her own. A police report earlier this year described the incident as a drowning, and authorities are investigating her death.

Relations between Nick Gordon and other relatives have soured over the past few years, especially after Bobbi Kristina Brown was hospitalized. A protective order barred him from being within 200 feet of Pat Houston. And a feud erupted over whether Nick Gordon could visit Bobbi Kristina Brown while she stayed in the hospital.

Fulton County District Attorney Paul Howard said he and his office are interested in reviewing the investigative file to determine whether any charges will be filed.

Leolah Brown said she believes Nick Gordon was involved in the death of Bobbi Kristina Brown.

Bobby Brown has paid tribute to his daughter Bobbi Kristina, describing her as “an angel”.

“Krissy was and is an angel,” Bobby Brown said in a statement.

“I am completely numb at this time. My family must find a way to live with her in spirit and honor her memory. Our loss is unimaginable.”

Bobbi Kristina Brown died on July 26 at the age of 22. She had been in a coma since being found face down and unresponsive in a bath at her Atlanta home on January 31.

Initial tests have found no significant injuries and no obvious underlying cause of death, according to the medical examiner.

Bobbi Kristina Brown was the only child of Bobby Brown and Whitney Houston.

Whitney Houston herself was found dead in a hotel bath in Los Angeles in 2012.

Bobbi Kristina Brown was found by her partner, Nick Gordon, in the bathroom of their home in Atlanta.

Nick Gordon’s mother, Michelle Gordon, said in a statement on July 27 that Bobbi Kristina Brown’s death had devastated her son and the rest of their family.

“Nick loved and cared for Krissi deeply, and he has suffered greatly each and every day they’ve been apart,” she said.

“Nick and our family are in mourning, and we ask that you respect our privacy. Our thoughts and prayers are with both the Houstons and the Browns during this difficult time.”

A police report described Bobbi Kristina Brown’s death as a “drowning” although it is unclear what led to it.

Bruising was found on the front of her body at the time. Authorities later said Whitney Houston’s daughter had sustained injuries in a car crash several days earlier, adding they were not the result of foul play.

Fulton County Medical Examiner’s Office said the time that had elapsed since the incident that led to Bobbi Kristina Brown’s death would “complicate” its effort to reconstruct events.

It said the initial portion of the post-mortem had been completed and there were no signs of “an obvious underlying cause of death”, no significant injuries and no previously unknown medical conditions.

The cause of death would not be announced until all tests have been conducted, it added, saying that could take “several weeks”.

A spokeswoman for Bobbi Kristina Brown’s family said she died on Sunday, July 26, surrounded by her family and was “finally at peace in the arms of God”.
