Bobbi Kristina Brown, Whitney Houston’s daughter, was allegedly found doing drugs yesterday, hours after her mother’s funeral.

Bobbi Kristina, 18, 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 Kristina went off to be alone and even caused panic this morning as Whitney Houston’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.”

The teenager 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.

Bobbi Kristina Brown 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.”

Bobbi Kristina had apparently grown up seeing her mother doing drugs and her family is concerned that she may follow in Whitney Houston’s footsteps in the more negative aspects of her life.

Although an associate of the Houston family told The Daily Beast that Bobbi Kristina went to rehab last year, the 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.”

But Bobbi Kristina was apparently left devastated after her father Bobby Brown walked out of the funeral yesterday with the nine guests he brought with him after he claimed he was asked to move by security three times.

“That was just too much for Bobbi Kristina to handle,” the source added.

“All that drama, and Cissy finally asked him to come in and stay, but Bobby wouldn’t.

“Cissy only did that to help Bobbi Kristina, because Cissy cannot stand Bobby.

“She just didn’t want a big drama with him on that day of all days.”

Bobbi Kristina is also apparently upset following her parents’ divorce in 2007 and how quickly Bobby Brown moved on.

Bobby Brown has become engaged and has a two-year-old little boy with fiancé Alicia Etheredge.

“There was some confusion about Bobbi Kristina’s whereabouts last night for a short time, but she’s OK,” a family spokesperson told The Daily Beast.

“She needed some time alone.”

The Houston family rep denied that Bobbi Kristina was on just and said that she was just going through a “very hard time as you can expect”.
