Whitney Houstan's daughter seen kissing 'adopted' brother

Singer Whitney Houstan's troubled teen daughter got into a bizarre relationship with her 'adopted brother'.

Nineteen-year-old Bobbi Kristina Brown and Nick Gordon, 22, have been seen kissing and holding hands at a store near their home. The youngsters have also been swapping a string of intimate tweets, reports thesun.co.uk.

Whitney, who was found dead in a hotel last month at Beverly Hills, started looking after Nick 10 years ago when his own mum was unable to care for him.

Nick lived with the singer and her daughter in Atlanta, but was not officially adopted.
