Bobbi Kristina Brown, the 18-year-old daughter of Whitney Houston and Bobby Brown, has been admitted to hospital twice since her mother was found dead Saturday afternoon in a bathtub at the Beverly Hilton. Sources told TMZ that the family fears she’s suicidal and they’re considering putting the teen into rehab to keep an eye on her. Bobbi Kristina was not in the hotel room when her mother died, and when she arrived, police officers would not allow her into the room. She got into a screaming match with them, demanding to see her mother, but was turned away. She was taken to the hospital that evening but released, then admitted again the following morning. Meanwhile, her father cancelled a concert in Nashville yesterday to fly to Los Angeles to be by his daughter’s side.
