Houston's daughter doing 'much better'

New York -  Bobby Brown says daughter Bobbi Kristina is doing "much better" after being hospitalised following the death of her mother, Whitney Houston.

The 18-year-old was taken to a Los Angeles hospital on Sunday after Houston's death the day before.

A source close to the family who spoke on condition of anonymity previously told The Associated Press the teen was treated and released for stress and anxiety.

In a statement on Wednesday, Brown said the family is providing "love and support" to Bobbi Kristina and pleaded for privacy. He says she's still dealing with the tragedy and "would prefer to do it outside the public eye".

Bobbi Kristina is Houston's only child.
