Whitney Houston and Bobby Brown’s daughter was found unconscious in a bathtub in her home — and taken to a hospital where she is now breathing …

Bobbi Kristina Brown’s husband Nick Gordon and a friend found her in the tub … according to police in Roswell, GA. We’re told her husband and friend immediately started CPR on her … until police and paramedics arrived.

We’re told police took over life-saving measures on the scene — and then she was taken by ambulance to a hospital.

Doctors have now stabilized her breathing, and we’re told she is in ICU.

Still unclear why Bobbi fell unconscious. We’re told a friend made the call to 911 from Bobbi’s house.

The circumstances are especially eerie — Whitney died in a bathtub at the Beverly Hilton on February 11 … three years ago.
