As Bobbi Kristina Brown remains hospitalized, her father’s attorney said “we are currently investigating the events that led to (her) hospitalization.”

Attorney Christopher Brown also said Tuesday that the 21-year-old daughter of singers Whitney Houston and Bobby Brown “is not and has never been married to Nick Gordon,” contrary to some reports.

Bobbi Kristina Brown was found facedown in a bathtub over the weekend. Her family has been tight-lipped about her condition, but her R&B singer father issued a statement through his lawyer Tuesday night.

“We continue to request privacy in this matter. Please allow for our family to deal with this matter and give Bobbi Kristina the love and support she needs at this time,” Bobby Brown said in the statement.

After she was discovered unresponsive in her home in the Atlanta suburb of Roswell, Brown was rushed to a hospital, where doctors placed her in a medically induced coma. As of late Monday, she remained on a ventilator in the intensive care unit, a source close to the family said.

On Tuesday, she was moved to Atlanta’s Emory University Hospital, sources close to the family said.

The status of her brain function won’t be known until sedatives are reduced, the source told CNN.

“Bobbi Kristina is fighting for her life and is surrounded by immediate family. As her father already stated, we are asking you to honor our request for privacy during this difficult time,” the Houston family said, thanking her supporters.
