Whitney Houston was known for her close bond with daughter Bobbi Kristina Brown. But a new Reelz series special, "Autopsy: The Last Hours of Bobbi Kristina Brown", has unveiled the bitterness behind the mother and daughter's relationship.

In a trailer obtained by Radar Online, celebrity expert Ian Halperin claimed Bobbi Kristina once tried to stab her mother. The incident occurred when Bobbi Kristina was just a 14-year-old girl. After trying to kill her own mother, she slit her own wrist which led her into hospitalization back in 2008.

"She knew her mother was a ticking time bomb because of all the drugs, all of the emotional fragility," he said on the special. "She would try not to go against her, although there were a couple of times when violence broke out. She once tried to stab her mother!"

On the series, British forensic pathologist Dr. Richard Shepherd also explained his findings on Bobbi Kristina's autopsy report. The report said that the daughter of the "I Will Always Love You" hitmaker had at least 30 scars on her body.

"Most of these are small parts of the everyday wear and tear of life," he said. "But there is a group of four scars on her forearm that I think are significant. I think these are evidence of self-harm, possibly even a suicide attempt."

Although every evidence found led to a suspicion of suicide attempt, Bobbi Kristina's father Bobby Brown still couldn't accept the death of his daughter. Bobby blamed her daughter's boyfriend Nick Gordon for her death as he claimed Nick kept giving her daughter "a toxic combination of drugs and alcohol" before she was found unconscious in her bathtub.

"Autopsy: The Last Hours of Bobbi Kristina Brown" premieres on Saturday, February 11 at 8 P.M. ET/ PT on Reelz.
