Whitney Houston's mother visits Bobbi Kristina Brown in hospital
Whitney Houston's mother has visited the hospital in Atlanta, Georgia, where the late singer's daughter is being treated after she was found unresponsive at her home.
Cissy Houston arrived at Emory University Hospital at around 1.30pm local time on the third anniversary of Whitney Houston's death.
Bobbi Kristina Brown has been in hospital since January 31, when she was found face-down and unresponsive in a bathtub in her home just north of Atlanta.
Whitney Houston was found face-down and unresponsive in about a foot of water in a bathtub in the Beverly Hilton hotel on February 11 2012, just before the Grammys.
She later died, and authorities concluded she had accidentally drowned. Investigators found a dozen prescription drug bottles in the suite and listed heart disease and cocaine use as contributors to her death.
