According to the Roswell, Ga. police, Brown's husband Nick Gordon discovered her and immediately began CPR on Brown with help from a friend. Police and paramedics arrived shortly after and took Brown, 21, to a hospital where she is now recovering in the ICU.
It is unknown why Bobbi Kristina fell unconscious.
In February 2012, Brown's mother Whitney died after being found unconscious in a hotel bathroom. Houston's cause of death was drowning, but a toxicology report showed she had cocaine, marijuana, Xanax, Benadry and other medication in her system.
"Obviously we all know her mom died this very same way," Lisa Holland of the Roswell Police Department told People.
