The 'My Prerogative' singer and Bobbi's late mother Whitney Houston have both struggled with drug addiction and although the 19-year-old starlet has been forced to deny rumours she has also been abusing illegal DRUGS, Brown believes she is ''smart enough'' not to follow in his footsteps.
He told MTV: ''Any parent that has a teenager in their life, they go through things. They go through phases that they might not be doing exactly what you want them to do in life, but they grow out of it, and my baby girl has grown out of it. I trust and believe that she's smart enough to not go down the same road that maybe I did in the past or her mother did in the past. She's extremely smart.''
Bobbi is focusing on launching an acting and music career since her mother died of accidental drowning caused by cardiac failure after taking cocaine in February and her dad is extremely proud of his daughter.
He said: ''That's my baby girl. She'll forever be my baby girl. She's doing what she's doing, and I'm extremely proud of her. She's acting and she's working on music and she's doing what she has to do to recover from her loss - our loss.''
While father and daughter have a difficult relationship, Bobby has denied reports that his daughter wants to ditch the surname Brown.
He said ''She can't change her last name, her name is her name. She'll forever be known as Bobbi Kristina Brown. There's no changing that, there's no taking that back.''
