Bobbi Kristina is said to be angry over her grandmother, Cissy Houston's, attempts to alter her allowance from her late mother, Whitney Houston's, estate.
Cissy filed legal documents requesting changes be made because she is worried about the bad influences in her grandaugter's life and feels she is not making wise decisions on how to spend her money.
"Bobbi is extremely angry at her grandmother for filing legal docs asserting that she is essentially hanging around with losers and [drug] users," a source told Radar Online.
"Cissy has made it known that she is extremely unhappy with the presence of Nick Gordon, Bobbi's 'boyfriend/brother' in her granddaughter's life.
Adding: "Right now Bobbi has absolutely no contact with her, Cissy or her aunt, Pat Houston. If Bobbi has concerns about payments from her mom's estate, she calls her lawyer."
Bobbi Kristina is rumoured to be engaged to her "adopted" brother Nick Gordon, and the pair become inseperable since Whitney's death, from drowning in a bathtub, in February.
The young couple were involved in a car crash last week in LA, but luckily escaped unharmed.
