Whitney Houston and her daughter Bobbi Kristina 'shared the same drug dealer'

A shock new report claims that the late Whitney Houston and her teenage daughter Bobbi Kristina shared the same drug dealer

A shock new report claims that the late Whitney Houston and her teenage daughter Bobbi Kristina shared the same drug dealer.

 Mother and daughter were using a man 'by the name of Jay' to purchase drugs right up until the singer's death last month.

A family insider allegedly told the publication that the man would deliver marijuana and cocaine to the Houston home in Atlanta, and that Whitney was taking drugs for 'most of the last six months of her life.'

A family insider allegedly told the publication that the man would deliver marijuana and cocaine to the Houston home in Atlanta for both mother and daughter

'Her regular dealer toward the end was a big black guy called Jay.

'He would call at the house most evenings in the months leading up to Whitney's death.

'And he earned a fortune from her.'

The reports claims that Whitney never had any interaction with the man and rather had a friend make the deals.

'They would hand Jay a brown paper bag crammed with hundreds of dollar bills and Jay would hand back the bag with the top folded down,' the insider claims to the British paper.

But while the dealings were taking place, the insider alleges that Whitney's 18-year-old daughter was also being given drugs and alcohol by that man, unbeknownst to her mother.

The new report comes after numerous reports about Bobbi Kristina's past troubles.

The teen was admitted to a psychiatric ward in 2008 after she tried to stab her mother during an argument before turning the blade on herself and trying to slit her wrists.

She had apparently grown up seeing her mother doing drugs and now her family are concerned that she may follow in the singer's footsteps in the more negative aspects of her life.

A year ago Bobbi's ex-boyfriend of more than two years was so concerned he spoke to Radar Online about her growing cocaine addiction that he says is due, in part, to her parents enabling her habits.

'I've tried to stop her, but all she said was, "I'm just like my mother!," he said. 

'It was difficult to stop her from buying alcohol and drugs because her mother gave her $1,000 a week. I saw Krissi do an eight ball - an eighth of an ounce - of cocaine in just two days with friends. One time Whitney bought a case of beer for Krissi and her friends to drink in front of her. I couldn't believe it!'

Last March, Bobbi took to Twitter to deny claims she had checked into rehab after The National Enquirer published pictures that allegedly showed her snorting lines of cocaine.

'Excuse me,' Bobbi Kristina tweeted, 'but I'd like to say that I am NOT going to rehab? I'm perfectly healthy and I am not addicted to anything but life.'

Long-time Houston family friend BeBe Winans said he wasn't aware of any alleged drug problems the teen was facing.

He recently told Access Hollywood: 'I don't know anything about rehab. I can tell you from being around her, pretty much all her life, and at the same time being around her in this dark valley, she's doing wonderful. She's doing wonderful.

Bobbi will sit down with Oprah on Sunday night for her very first interview since her mother's death. 

Joining Bobbi will also be Patricia Houston, Whitney's sister-in-law and one-time manager.

In the interview Oprah asks her whether she thought drugs were the cause of her sister-in-law's sad demise. 

'The handwriting was kind of on the wall,' she said. 'I would be kidding myself to say otherwise.'

But Patricia thought that before Whitney's death, the singer was somewhat safer that she was before.  

If things hadn't changed, but things were changing, things were really changing with her, very much so,' she said. 

'It wasn't about the substance abuse or anything like that relative to the latter days or anything like that, I think it was more of lifestyle.

'I was afraid for other things, lifestyle more so than...' she trailed off. Not letting a tease like that go unanswered, Oprah pressed her on what, exactly, it was about her lifestyle that seemed so threatening

'I saw her chasing a dream, looking for love in all the wrong places.'
