Bobbi Kristina Brown, the daughter of late singer Whitney Houston, has died at the age of 22 - six months after she was found unresponsive in a bathtub at her Atlanta home.
Ms Brown had suffered irreversible brain damage when she was discovered on 31 January.
She spent months in a medically induced coma and was moved into hospice care in June, but never regained consciousness.
The incident was described as a "drowning" in a police report, and Ms Brown was breathing with the aid of a ventilator.
Her death was confirmed in a statement on Whitney Houston's official Facebook page, which read: "It is hard to say goodbye".
"On Sunday, July 26, Bobbi Kristina Brown made her transition peacefully. The family thanks everyone for their loving thoughts and prayers.
"As Bobbi Kristina would say: 'The wind is behind me and the sun is in my face'."
Ms Brown was being treated at the Peachtree Christian Hospice in Duluth, Georgia, and her relatives had been keeping a daily vigil at her bedside.
In February 2012, her mother Whitney Houston died aged 48 from accidental drowning in a bathtub at a hotel in Beverly Hills, California.
Authorities said years of cocaine abuse and heart disease played a key role in Houston's death.
Bobbi Kristina - referred to as Krissy by family members - was the only child of Houston and Bobby Brown, and was treated in hospital twice for anxiety after her mother passed away.
In an interview with Oprah Winfrey shortly after her mother's death, Ms Brown had spoken of her aspirations to carry on her mother's legacy by forging a career in dancing, acting and singing. However, her career never took off.
Jeanne Wolf, a Hollywood reporter who had met Bobbi Kristina and her late mother, told Sky News that the young woman's death was "a long time coming".
The journalist explained: "She never had anything that approached a normal life. She was surrounded by a husband and wife that were fighting, she was surrounded by drugs and people trying to get off drugs.
"None of this is wholesome living, none of this is something you can say with a smile.
"She strived to be something she could never be, which is to have the career that Whitney - one of the most beautiful people on the planet, and certainly one of the most talented - had.
"Bobbi Kristina just couldn't live up to that."
After news of the young woman's death emerged, Winfrey tweeted: "Peace at last!"
The Grammy-winning performer Missy Elliot tweeted: "My heart is truly heavy. May u rest in peace with your mommy #BobbiKristina sending prayers 2 the Brown/Houston family."
