ATLANTA

The daughter of late pop star Whitney Houston and singer Bobby Brown was placed in a coma to stop brain swelling after she was found facedown and unresponsive in a bathtub in her Georgia home last weekend, family friend and gospel singer Kim Burrell told “Access

Hollywood.”

Bobbi Kristina Brown, 21,

was moved Monday to Emory University Hospital from a hospital in the Atlanta suburb of Roswell, where she was taken after being discovered in the tub by her husband, Nick Gordon, on Saturday.

In a statement Monday, her family said they were by her side as she fights for her life.

According to reports, her father, Bobby Brown, maintains a constant vigil by her bedside. “He’s so upset. He can hardly put one foot in front of the other,” it’s been reported.

Reports also have said she suffered an accidental drug overdose and that authorities found drugs in Bobbi Kristina’s apartment home while performing a second search of her residence.

Meanwhile, police say her former boyfriend, Maxwell Lomas, also was in her apartment when she was found unresponsive. He had been arrested last month on drug distribution charges.

The 24-year-old tree removal crew member was arrest-ed last month and charged with possession of marijuana

with intent to distribute, possession of the anti-anxiety drug Xanax and possession of a firearm or knife during the commission of or attempt to commit certain felonies, Fulton County Jail records show.

He was released on bail Jan. 18 on a $15,000 bond, three days after he was booked on the charges.

Ms. Burrell told the entertainment television program on Monday that Bobbi Kristina’s loved ones were hoping for the best after doctors put her in a medically induced coma.

“Her eyes did move a little bit,” Ms. Burrell said. “We’re hoping that it’s just not a reflex. We’re hoping that it’s a conscious choice.”

The circumstances are reminiscent of Ms. Houston’s death nearly three years ago. The megastar pop singer and actress drowned in a hotel bathtub in Beverly Hills, Calif., on Feb. 11, 2012. Authorities said cocaine use and heart disease contributed to the six-time Grammy Award winner’s death at age 48.

Ms. Houston won accolades for hit songs, including “I Will Always Love You” and “I Wanna Dance With Somebody (Who Loves Me).”

She divorced Bobby Brown in 2007 after a stormy 15-year marriage during which both spouses struggled with substance abuse. Mr. Brown, also a Grammy Award winner, started his career as frontman for the R&B group New Edition.
