BOBBI Kristina Brown's family and friends reportedly staged a failed intervention for the teenager.
The 19 year old's loved ones have been very worried about her behaviour since the death of her mother Whitney Houston in February as she has allegedly been taking prescription pills, drinking heavily and smoking marijuana to cope with her loss.
According to America's Star magazine, Bobbi's aunt Pat recently arranged for several close family members and pals of the youngster to speak to her about her substance use, but their words fell on deaf ears.
A source said: ''Everyone is worried sick about Krissy ... her aunt Pat got a number of her friends and family to come to Atlanta and have a serious talk with her about her sobriety.
"There were lots of tears, but Bobbi Kristina didn't listen.''
Pat has even asked Whitney's long-term mentor Clive Davis to speak to Bobbi - whose father is the late 'Million Dollar Bill' singer's ex-husband Bobby Brown - about her problems in a bid for to alter her lifestyle.
The source added: ''Clive keeps telling Bobbi she needs to go to rehab, and that if she does, he'll help launch her music career. He's doing everything he can.''
Whitney died from accidental drowning due to the effects of heart disease and cocaine use in February aged 48.
She had a long history of substance abuse and had admitted to Oprah Winfrey she took cocaine in a candid 2009 interview.
