Reportedly, BOBBI KRISTINA disappeared from mom WHITNEY HOUSTON’s funeral only to be found “getting high”.

I’m just like my mother,” Whitney Houston’s daugh­ter Bobbi Kristina once told a friend.

And for a while, Krissi, as she’s known to family and friends, appeared to be headed down the same destructive path that her mother walked.

The only child of Whitney and ex-husband Bobby Brown – who turns 19 on March 4 – has had troubled teen years, marked by cocaine use and heavy drinking.

She’s even been arrested following a violent incident where a gun was pulled.

The first sign of problems occurred when Krissi was only 12 and she was photographed drinking from a wine glass while her parents looked on.

Then, on Feb. 17, 2008, tortured by the divorce of her parents the year before, Krissi tried to stab Whitney during a heated argument over her behavior, and then tried to commit suicide by slashing her wrists, The ENQUIRER reported exclusively.

“Bobbi Kristina has been running around drinking and par­tying, doing whatever she wants to do,” family member Ann Davis said at the time.

Krissi was admitted to a psychiatric ward at Peachford Hospital in Atlanta and Ann said she refused to have either Whitney or Bobby visit her.

The wild child’s antics only got worse. In our March 14 issue last year, we showed shocking photographs of Krissi snorting lines of cocaine at two different parties in Alpharetta, Ga., just a few miles from where she lived with her mother.

A former boyfriend, who dated her for two and half years and took the photos, told The ENQUIRER at the time: “Krissi is addicted to cocaine. I’ve tried to stop her, but all she said was, ‘I’m just like my mother!’ If Krissi doesn’t stop soon, cocaine will kill her!”

The boyfriend said booze played a major part in Krissi’s life when they first met.

“We had mutual friends. We planned to look out for each other. But when I met Krissi at one party, she was drunk on Everclear (grain alcohol) and she’d already made out with three of my friends.

“Despite that, we began to date, but during the first few months I knew her, I can’t remember a time that she stayed sober all day.

“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

eightball – pieces of cocaine weighing an eighth of an ounce each – in just two days with friends.”

The boyfriend said Whitney originally did nothing to stop Krissi from drinking and taking drugs.

“One time Whitney bought a case of beer for Krissi and her friends to drink in front of her. I couldn’t believe it!” he said. “She also had a Xanax prescription and was addicted to that. Once she had a meltdown because she’d run out, and Whitney found a pill to give her.”

All the while, Whitney and Bobby just blamed each other for Krissi’s behavior.

In shame, Whitney shelled out $49,000 to enroll Krissi in an outpatient program at Talbott Recov­ery in Atlanta. The treatment was short-lived.

“Whitney pulled Krissi out of the program after one day because she was afraid of what Krissi would tell the other addicts about her in group sessions,” a source said. “Krissi had been fighting rehab anyway, saying she’s not addicted to cocaine.”

The ENQUIRER also revealed that a boozing Krissi was arrested when she got caught up in the middle of a terrifying incident in Roswell, Ga., on April 1 last year.

The blowup involved Krissi’s ex-boyfriend Max Lomas and another teen, Nicholas Gordon.

A police report obtained by The ENQUIRER described how Lomas and Gordon – who told police he was Krissi’s brother – were angered after seeing Krissi driving with three male friends and followed them in Gordon’s car to a Chevron gas station.

At the gas station, Lomas allegedly beat up one of Krissi’s friends. Gordon admitted to police he waved a gun in the air during the fight.

Police later found a Glock 19 handgun in his glove compartment.

Krissi was handcuffed and cited as a minor in possession of alcohol, Nick Gordon was charged with pointing a pistol at a person and Lomas was charged with battery.

The incident seems to have scared Krissi straight. And in truth, she dearly loved her mom. In the past months, she has happily joined her mom on stage at performances and even sang a few duets with her.

Krissi was thrilled that Whitney took her along to the Beverly Hilton, where they looked forward to attending the Grammy Awards show together.

Now friends are scared that Whitney’s death will push Krissi down the same slippery slope of drug abuse.
