Bobbi Kristina Brown: Cissy Houston blames Bobby Brown for daughter Whitney Houston's death?

As Bobbi Kristina Brown remains unresponsive in hospital, Cissy Houston has opened up about her granddaughter's tragic condition and recalled the heartbreak of losing her daughter Whitney Houston in similar circumstances.

In an interview with Entertainment Tonight, the Houston matriarch said that the late singer, who was found unresponsive in a bath at a Beverley Hills hotel on 11 February 2012, was her pride and joy.

"She's my baby," Houston said. "I had two boys before her and I never wanted boys. I love them. They know I love them. But I always wanted a daughter."

Houston also claimed that it was unfortunate that her daughter lost her way in the entertainment industry and married Bobby Brown.

"This business is really bad, you know what I'm saying?" she said. "But she did the best she could."

The 81-year-old, who is reportedly embroiled in an ongoing feud with Brown over Bobbi Kristina's condition, went on to suggest that Houston would have had a better chance with the right partner.

"My baby tried. She did. She just had the wrong partner, you know?" Houston said of Brown. "Whitney was a very soft and easy person. ... She was kind. She was free-hearted. All of that, and sometimes people didn't treat her nice."

Bobbi Kristina has been in hospital since 31 January after she was found unconscious in a bathtub at her home in Roswell, Georgia.

In April, Brown stunned fans when he claimed that Bobbi Kristina was "awake", telling the crowd at concert in Texas: "I can say today: Bobbi is awake. She's watching me."

But in a statement released to People Magazine, Houston shattered any hope of a full recovery by revealing that doctors said she had "irreversible brain damage".

A judge has since appointed Brown and Whitney's sister-in-law Pat Houston co-guardians of Bobbi Kristina's estate.

"Both Mr Brown and Ms Houston are jointly responsible for decisions related to Krissi's care and medical needs," their respective lawyers said in a statement. "Both parties are delighted with the court's decision and are working harmoniously to ensure Krissi receives the best possible medical care."

The move, which means that the pair have joint control over her $20m (£12.7m) inheritance, followed an alleged dispute between Houston and Brown over the 22-year-old's estate.

According to Radar Online, a family source said: "Cissy Houston will fight this to the grave. Since day one, all of the Houstons have been waiting for Bobby to try and get Bobbi Kristina's money and they knew it was just a matter of time. No one is surprised that he is making a grab for her money."
