bobbi kristina & nick gordon*Bobbi Kristina doesn’t think her daddy, Bobby Brown, is conquering his demons.

TMZ caught up with her as she was leaving LAX with her “brother” Nick Gordon. They asked if her father is “rising above” his alcohol issues now that he’s checked himself into rehab.

“‘Rise above’ is not the word you should use” … Bobbi told us … “Not at all.”

Her response flies in the face of the singer’s wife and lawyer who released a statement earlier today saying Brown was “doing well in rehab.”

As we reported, Brown checked himself into a treatment center earlier this week after struggling with booze for years and getting a DUI back in March.
