Bobbi Kristina Brown

Bobbi Kristina Brown, Her mother’s funeral had just been hours before, but Whitney Houston’s daughter Bobbi Kristina Brown was allegedly found doing drugs yesterday.

The 18-year-old apparently slipped away from friends and family after the emotional four-hour home going service in New Jersey.

Instead of joining them at a restaurant in Newark, Bobbi went off to be alone and even caused panic this morning as her mother’s coffin was being transported to the Fairview Cemetery to be buried.

‘Everyone was freaking out and calling Bobbi Kristina’s cell,’ a family friend told The Daily Beast.

‘It was so much commotion and activity after the funeral that Bobbi Kristina just slipped away. Ms. Cissy [Houston] was beside herself.’

Bobbi Kristina was understandably left devastated when her 48-year-old superstar mother was found dead in a bathtub at the Beverly Hilton hotel on February 11.

She was apparently found ‘getting high’ after she received the news her mother had passed away and there were conflicts between family members on whether she should be taken to rehab straight away or left to mourn with her family.

‘It’s a horrible situation for everybody,’ the family friend said. ‘They tried to save Whitney, and it didn’t work. Now with Bobbi Kristina, they fear the same thing is happening again and they wont’ be able to stop it either.’

‘Bobbi Kristina is all Ms. Cissy has left of Whitney. She’s so tired, but she’s ready to fight again to save her grandbaby.’

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

Although an associate of the family told The Daily Beast that Bobbi Kristina went to rehab last year, the Houston family would not be drawn on the matter.

‘Bobbi Kristina had the people she loved and love her the most around,’ the source said in the days before the funeral. ‘Ms. Cissy was holding on tight and watching her every move.’
