Whitney Houston’s daughter Bobbi Kristina Brown found unresponsive in bath

Bobbi Kristina Brown, the only daughter of the late pop star Whitney Houston and singer Bobby Brown, is recovering in hospital after she was found unresponsive at her home on Saturday.

Police are investigating if drugs were involved after the 21-year-old was revived and rushed to a hospital after she was found in the bathtub by her husband.

The incident comes nearly three years after Houston, a superstar who battled substance abuse, drowned in a bathtub in Beverly Hills, California, in February 2012. Authorities determined cocaine use and heart disease contributed to her death.
