Bobbi Kristina Brown Update: Nick Gordon’s Brother Claims Their Drug Use Started With Whitney Houston

Bobbi Kristina Brown and her boyfriend Nick Gordon began using drugs at home with the late Whitney Houston, Gordon’s brother, Jack Walker, claimed during a recent interview. Walker also reportedly claimed that Bobbi Kristina had tried to commit suicide.

Walker’s interview with Extra TV comes days after conflicting statements from the Brown and Houston families over the 22-year-old’s current medical condition. Walker reportedly claimed that he had closely witnessed Bobbi Kristina and Gordon’s drug use at her Atlanta home, adding that he chose to stay out of it because he was not comfortable using drugs.

“I let Nick know, slow down on that. You need to stop doing that,” Walker told Extra TV. “It was going on when Whitney was alive. I would be on the phone with Nick and I can hear Whitney asking for the stuff.”

Walker also reportedly stated that Bobbi Kristina was depressed because of an argument she had with Gordon and might have tried to commit suicide. The aspiring actress was found unresponsive in a bathtub at her Atlanta home on Jan. 31, following which she was hospitalized and put in a medically induced coma.

“I just feel like she… she just was fed up with everything that's going on in her life,” he reportedly said.

Steven Stepho -- a friend of the aspiring actress and Gordon -- alleged last month that the couple had spent thousands of dollars a day on drugs. Gordon, who has been under criminal investigation after injury marks were found on Bobbi Kristina’s body, opened up about his drug use during an interview with Dr. Phil before heading to rehab.

“He's been off of drugs for almost seven weeks. He's actually surprised that he stayed, to be honest with you,” Walker said, during the interview. “He's like, ‘I'm proud of myself for staying, I didn't think that I'd be able to do it.’ He's not the same person he was when he went in.”

The Houston family had confirmed earlier this week that Bobbi Kristina is off life support and is breathing on her own. Bobbi Kristina's father, Bobby Brown, also released a statement through his lawyer stating that his daughter had recently shown signs of improvement.

Whitney's mother, Cissy Houston, later claimed that while her granddaughter's condition had improved, the brain damage Bobbi Kristina sustained is “irreversible” and that she remains unresponsive.
