NEW YORK • Bobbi Kristina Brown, the only child of pop stars Whitney Houston and Bobby Brown, died on Sunday. She was 22.
She set off a media frenzy after she was found unconscious in a bathtub on Jan 31.
Her death was confirmed by a statement from the Houston family provided by their representatives.
"She is finally at peace in the arms of God," said the statement, which added that she was surrounded by loved ones as she slipped away.
She died after her family decided to "take her off all meds", said celebrity website TMZ.com.
Brown, who grew up in the shadow of her parents' fame and tumultuous relationship and was the sole heir to her mother's estate, was found in her townhouse in a suburb of Atlanta on Jan 31 and placed into a medically induced coma.
The circumstances were reminiscent of those surrounding her mother's death. Houston was found submerged in a hotel bathtub in Beverly Hills, California, on Feb 11, 2012.
Houston was one of the foremost pop stars of the 1980s and 1990s. Her career deteriorated as she and Bobby Brown struggled with drug and alcohol addiction, and their marriage ended in 2007. In a 2009 interview with Oprah Winfrey, she said their passionate marriage degenerated into physical and psychological abuse from Brown.
Bobbi Brown was an aspiring singer who began performing with her mother as early as 1999, singing duets of My Love Is Your Love. In 2003, they recorded another duet of Little Drummer Boy for a holiday album.
Brown also appeared on reality shows such as Bravo's Being Bobby Brown (2005), about their dysfunctional family and Lifetime's The Houstons: On Our Own, about their grief after Houston's death.
She was the sole heir to her mother's estate, widely reported to be about US$20 million (S$27 million), which was put into a trust to be paid out in instalments to her. People magazine reported in March that her uncle and aunt, Gary and Pat Houston, were in charge of managing the trust.
Conflicting news reports and family statements about her condition swirled for months. She was placed into hospice care on June 24.
Her conservator Bedelia Hargrove filed a lawsuit on her behalf on June 25 against Nicholas Gordon, variously described in news media accounts as Brown's boyfriend, fiance or husband.
The suit charges that he physically abused her and misrepresented himself as her husband to embezzle her funds. It also contends that the two had a loud argument before he and a friend found her in the bathtub on Jan 31.
The lawsuit also claims that Gordon stole more than US$11,000 from Brown's accounts while she was in a coma.
Mr Randy Kessler, Gordon's lawyer, said in a text message on Sunday night: "Sorry. I have no comment right now."
Brown's survivors include her father; her grandmother, singer Cissy Houston; and her uncle and aunt.
