Bobbi Kristina Brown, daughter of the late entertainer Whitney Houston and R&B singer Bobby Brown, has died, seven months after she was found face-down in a bathtub. She was 22 years old.

A representative for the Houston family, Kristen Foster, said: "Bobbi Kristina Brown passed away July, 26 2015, surrounded by her family. She is finally at peace in the arms of God. We want to again thank everyone for their tremendous amount of love and support during these last few months."

Police said she was found on January 31 in the suburban Atlanta home she shared with Nick Gordon, the man she called her husband. A police report described it as a "drowning".

Bobbi Kristina was the only child of Houston and Brown.

She was in hospital for months in Atlanta - eventually being placed in hospice care - after being found in a manner similar to the way her megastar mother died three years earlier.

Mr Gordon said at the time it seemed she was not breathing and lacked a pulse before help arrived.

Bobbi Kristina appeared alongside both parents in 2005 on the Bravo reality show Being Bobby Brown, which captured her parents fighting, swearing and appearing in court.

Years earlier, as Houston was preparing to give birth to Bobbi Kristina, she expressly left Bobby Brown out of her will, putting everything in a trust "for the benefit of her children and more remote descendants".

After their divorce in 2007, Houston kept custody of Bobbi Kristina and raised her alongside Mr Gordon, an orphan three years older than her daughter. Houston brought him into her family, and while she never formally adopted him or included him in the will, both teenagers called her "mom".

Houston's assistant found the singer's lifeless body face-down in a foot of water in her bathtub at the Beverly Hills Hotel just before the Grammy Awards in 2012. Authorities found prescription drugs in the suite, and evidence of heart disease and cocaine in her body, but decided it was an accidental drowning.

Bobbi Kristina, then 18, was at the hotel and became so hysterical she had to be taken to hospital.

She and Mr Gordon then went public with their romance, posting defiant messages online after the tabloids accused them of incest.

By January last year, the young couple who grew up as brother and sister were sharing a home and calling themselves husband and wife.

They posted images of their hands wearing wedding rings, with the caption "#HappilyMarried. So #InLove. If you didn't get it the first time that is" and got identical "WH" tattoos with flying doves on their wrists.

Relations between Mr Gordon and some relatives soured this year while Bobbi Kristina was in hospital. A protective order barred him from being within 200 feet of Pat Houston, Bobbi Kristina's aunt. A feud erupted over whether he could visit Bobbi Kristina while she was in hospital.

On June 24, Bobbi Kristina's court-appointed representative sued Mr Gordon, accusing him of misrepresenting his relationship with Bobbi Kristina. The complaint accused him of being violent toward her and taking more than $11,000 from her account while she was in a medically induced coma.

The lawsuit accused him of assault, battery, intentional infliction of emotional distress, unjust enrichment and conversion.

Fulton County District Attorney Paul Howard said he and his office are interested in reviewing the investigative file to decide whether any charges will be filed.

Bobbi Kristina was fabulously wealthy for a teenager, but her money was in a trust, designed to keep creditors and predators from taking advantage of people who cannot manage their money.

Her grandmother, Cissy Houston, and Pat Houston, eventually took over control of the trust and then took Bobbi Kristina to court to protect the estate.

As the news of the death spread across social media, celebrities began to tweet their condolences.

Grammy-winning performer Missy Elliot said: "My heart is truly heavy. May u rest in peace with your mommy ... sending prayers 2 the Brown/Houston family."

Empire star Taraji P Henson tweeted: "Rest in heaven."

And Oprah Winfrey tweeted: "Peace at Last!"
