Bobbi Kristina reportedly on ventilator as Bobby Brown is by her side

Luther Vandross was outed as gay after his death.

Bobby Brown arrived at Bobbi Kristina Brown’s bedside Saturday evening, according to TMZ. The celebrity news site says that Tyler Perry offered to take the 90s R&B artist on a flight from Los Angeles to Atlanta to see his only daughter by the late Whitney Houston.

Doctors have placed Bobbi Kristina in a medically induced coma to prevent brain swelling. However, ET is reporting that a close family member has told them that the 21-year-old has been placed on a ventilator. The machine is used on patients who are unable to completely breathe on their own.

Their source also tells them that this is not an attempted suicided but is being investigated by police as a drug overdose.

Saturday morning, rescue workers were sent to Brown’s home in Roswell, Georgia, at 10:25am after her husband, Nick Gordon, and a friend found her in the tub. The two tried to administer CPR. Police arrived on the scene and also tried to resuscitate Brown until the Roswell Fire and Rescue personnel arrived.

Bobbi Kristina was reportedly discovered face down in the bathtub, and police searched her home for drugs.

Officer Lisa Holland, a police spokeswoman, told CBS Radio News. “We are interviewing all the family members and friends.”

Bobbi Kristina most recently made headlines when she and her family criticized Angela Bassett for her depiction of Whitney Houston in a Lifetime biopic. The made-f0r-TV movie aired two weeks ago.

Nearly three years ago to the day, 48-year-old Whitney Houston was found face down and unresponsive in a hotel bathtub. Her death on Feb. 11, 2012, was attributed to drowning, but authorities also said that heart disease and cocaine were contributing factors. Dozens of prescription drug bottles were found in Houston’s hotel suite.

ET says a source close to the family told them that it’s “no coincidence” that Bobbi Kristina was found in circumstances that resembled her mother’s death. They said that Brown’s troubles are “a lot deeper than everyone can see.”
