Bobbi Kristina Brown, the daughter of late music legend Whitney Houston and R&B singer Bobby Brown, died on Sunday (July 26), aged 22.

Bobbi Kristina was surrounded by her family at Peachtree Christian Hospice in Duluth, Georgia, news site Entertainment Tonight reported.

"She is finally at peace in the arms of God," the Houston family said in statement to the site.

"We want to again thank everyone for their tremendous amount of love and support during these last few months."

On Jan 31, Brown was found unresponsive in her bathtub, and was then taken to North Fulton Hospital in Roswell, Georgia, where she was put on a ventilator to assist her breathing.

She was later placed in a medically induced coma at Atlanta's Emory University Hospital. Nearly two months later, she was moved to a rehabilitation centre, where she remained until June 24, when she was moved to the hospice centre.

The discovery of Bobbi Kristina in the bathtub came just days before the third anniversary of her mother's passing. Entertainment Tonight reported that Bobbi Kristina suffered from an apparent drug overdose.
