WHITNEY & BOBBY OUT OF CONTROL DAUGHTER PARYTING LIKE A ROCKSTAR

Poor Lil Bobbi-Kristina might be headed down the same "CRACKHEAD" road as her recovering addicts parents. The wild child daughter of WHITNEY HOUSTON and BOBBY BROWN is going party-crazy - and sources say.

Shocking photos of 17-year-old Bobbi Kristina Brown at a boozy blowout have been posted online, prompting her worried mom and dad - who have both battled serious substance abuse issues - to intervene, insiders say.

"Whitney and Bobby sat Bobbi Kristina down and read her the riot act," a family friend told The ENQUIRER.  "They brought in counselors and they're trying to drum into her that because of their problems she's genetically predisposed to alcoholism and drug addiction.  "They'll do anything to spare Bobbi Kristina from the substance abuse hell they've both experienced."

As The ENQUIRER has reported previously diva Whitney, 47, has undergone treatment at least twice to kick a drug habit that cost more than $300,000 a year. AND Bobby, 41, has spent more than his fair share of time in rehab battling coke, booze and pot.

Insiders say that both Bobby and Whitney flipped when pictures surfaced of their daughter downing "blackout in a can" and was seen making out with a young woman at a party.

It's not the first time Bobbi Kristina's behavior has raised red flags. She tried to stab her mother in 2008 during a confrontation and spent days in a psych hospital after slashing both wrists.
