Whitney Houston's daughter, Bobbi Kristina Brown, was found unconscious in the bathtub of her Roswell, GA home this morning by her husband Nick Gordon. The 21 year-old was revived on the scene by paramedics and taken to the hospital where she is currently in intensive care.

The circumstances surrounding Bobby Kristina's medical emergency are unclear -- apparently a male friend made the 911 call from Bobbi's house.

Bobbi's mother Whitney was found dead in a hotel bathtub at the Beverly Hills 3 years ago on February 11.
