Whitney Houston and Bobby Brown are said to be teaming up for an intervention to save their out of control daughter Bobbi Kristina, who just turned 18 earlier this month and has been the subject of recent media attention regarding her alleged drug abuse.

In the days leading up to her 18th birthday on March 4th, the National Enquirer published photos of the teenage celebuspawn allegedly snorting cocaine. Now, just weeks later, a source tells the Enquirer that Whitney took away the brand new Lexus she bought her for her birthday, and she and Bobby are sending little Bobbi to an unnamed rehab facility.

Crushed by our report that her daughter – known to friends as “Krissi” – is hopelessly addicted to cocaine and alcohol, Whitney begged her: “Don’t let drugs ruin your life the way they ruined mine,” sources say. The Grammy-winning diva and her ex-husband, Krissi’s father Bobby Brown, are blaming each other for their only child’s problems, according to insiders.

“Whitney was devastated over the photos showing Krissi using cocaine, and The ENQUIRER story that quoted her telling friends, ‘I’m just like my mother,’” a friend divulged. “She called a family meeting and sobbed as she told Krissi, ‘I don’t want to lose you.’”

The singer, 47, also canceled plans to celebrate Krissi’s 18th birthday on March 4 in Atlantis, the luxury resort in the Bahamas, the source revealed. “Whitney called Bobby, and they agreed that Krissi needs rehab,” the friend said. “They also agreed on a tough-love move to shake Krissi up, and Whitney returned a Lexus convertible that she’d bought for Krissi’s birthday.”

Despite her parents’ decision, Krissi is fighting the idea of rehab, said the source. “Krissi is denying that she has a problem. She says that she does cocaine for fun and isn’t addicted,” said the source.

Meanwhile, Whitney and Bobby – who have both battled serious drug habits – are blaming each other for Krissi’s problems, sources say. “Bobby reminded Whitney that she used to have drugs all over their house,” a friend divulged.
“He also accused her of being ‘coked up’ in public, looking like a mess and setting a bad example all along to their daughter,” the friend said.

But “The Bodyguard” star was quick to snap back at her bad boy ex, said the source. “Whitney told Bobby that he did drugs too and got into more legal trouble than she ever did,” the friend said.

Bobby, 42, has been arrested for DUI, possession of marijuana, driving without a license, probation violations and misdemeanor battery for slapping Whitney. The former “New Edition” singer, who has five children with four different women, has also been dragged into court numerous times for failure to pay child support.

“Bobby and Whitney are pointing fingers at each other, but the truth is that they’re both responsible. Krissi has been around while her parents and their friends were drinking and drugging ever since she was a little girl,” said another pal. Krissi was only 12 when she was photographed drinking from a wine glass as her parents looked on.

In 2008 she was admitted to a psychiatric ward after attempting to slash her wrists with a razor blade. As The ENQUIRER reported, Krissi’s suicide bid came after she tried to stab her mother during a heated argument. And she was just 17 when a former boyfriend – who dated her for 2 1/2 years – snapped the coke-snorting photos that appeared in The ENQUIRER. He also claimed that he saw Krissi smoke pot and guzzle beer and the potent grain alcohol Everclear.

After The ENQUIRER’s explosive story hit newsstands, Krissi took to her Twitter account to blast her ex-boyfriend. But she admitted that it was her in the photos, and said her mother “comforted me to the max.”

Now with Bobby’s blessing, Whitney is planning to send Krissi to an outpatient rehab program, said the source.
