And this story just gets sadder by the minute….

Whitney Houston’s 18-year-old daughter, Bobbi Kristina Brown, was just rushed to Cedears-Sinai Hospital in Los Angeles … and it’s her second trip to the hospital since her mother passed away last night.

According to our sources … Bobbi was taken out of the Beverly Hilton on a stretcher (see photo above). It’s the same hotel where Whitney was found dead. Law enforcement sources tell TMZ police and fire responded to a call for a medical emergency, but would not confirm who was transported. According to our sources, Bobbi Kristina went to the hospital last night as well, but was not transported via ambulance. We’re told she was “hysterical, exhausted and inconsolable.” TMZ
