Whitney spirals out of control

Whitney Houston's sister-in-law Tina Brown has spoken out about the diva's dangerous crack habit in the National Enquirer, describing how Whitney spends days locked in a room, high on drugs and hallucinating. The interview was accompanied by photos of the star's bathroom - littered with a crack pipe, rolling papers, cocaine-soaked spoons and cigarette butts. She often disappears for days at a time, said Brown, and often ends up in seedy crack dens. "The truth needs to come out. Whitney won't stay off the drugs. It's every single day. It's so ugly. Everyone is so scared she is going to overdose," Brown told the paper. "She'll point to the floor and say, 'See that demon. I'm telling you somebody's messing with Bobby.' She always thinks it's something to do with Bobby. But it's her, hitting herself." Whitney's daughter Bobbi Kristina is often frightened by her mother's bizarre behavior. Brown also described an incident in 2003 where Whitney was rushed to hospital with blood gushing from her nose. "I understand what she's going through," Brown added. "Addiction is a disease. Maybe this interview will save her life."
