Bobbi Kristina Brown once tried to stab mother Whitney HoustonLos Angeles, Feb 11 (AZINS) Late singer Whitney Houston was known for her close bond with late daughter Bobbi Kristina Brown. However, according to celebrity expert Ian Halperin, Kristina Brown once tried to stab her mother.

The incident occurred when Kristina Brown was all of 14, Halperin has said in a new TV series "Autopsy: The Last Hours of Bobbi Kristina Brown", reports radaronline.com.

After trying to kill her mother, Kristina Brown slit her own wrist which led her into hospitalisation back in 2008.

"She knew her mother was a ticking time bomb because of all the drugs, all of the emotional fragility," Halperin said on the special show.

"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," he added.

On the series, British forensic pathologist Richard Shepherd also explained his findings on Kristina Brown's autopsy report. The report said that she had at least 30 scars on her body.

Kristina Brown died at the age of 22 in 2015.
