Brown, 18, was taken out of the Beverly Hilton — the same hotel where her mother was found unconscious and pronounced dead — on a stretcher Sunday, according to a photo obtained by TMZ.
Law enforcement sources told the site that police and fire departments responded to a call for a medical emergency, but would not confirm who was transported to Cedars-Sinai Hospital in Los Angeles.
According to TMZ, this was her second trip to the hospital after her mother's passing. She went late Saturday, but not by ambulance, because she was said to be "hysterical, exhausted and inconsolable," a source tells the site.
TMZ reported on Saturday that Brown got into a verbal argument with police officers outside her mother's hotel room when she was denied access to her mother's body.
Brown's father, Bobby Brown, was in Mississippi for a New Edition concert when Houston was pronounced dead. "I would like to say, 'I love you, Whitney,'" he told thousands of concertgoers Saturday evening, according to The Associated Press. "The hardest thing for me to do is to come on this stage."
The two were married for 15 years before divorcing in 2007.
