Bobbi Kristina Brown—the 21-year-old daughter of Whitney Houston and Bobby Brown—was rushed to the hospital on Saturday after she was discovered "unresponsive" in a bathtub, CBS reports.

According to TMZ, Brown's breathing has now been stabilized.

After calling 911, husband Nick Gordon* and a friend reportedly performed CPR on Brown until emergency personnel arrived at the Roswell, GA home where she was found.

Three years ago, Brown's mother died under strangely similar circumstances, accidentally drowning in a bathtub at the Beverly Hilton Hotel.

*UPDATE 2/07: According to father Bobby Brown's legal counsel, Bobbi Kristina was never legally married to Nick Gordon, who she had previously referred to on social media as her husband.
