Bobbi Kristina Brown dies at age 22.

Bobbi Kristina Brown, 22, the only daughter of singers Whitney Houston and Bobby Brown, died Sunday, nearly six months after she was found unresponsive in a bathtub of her home, her family said.

Brown has been unresponsive in hospitals and hospice care since she was found in her Roswell, Georgia, home on Jan. 31. Her family said she suffered irreversible brain damage.

"She is finally at peace in the arms of God," her family told NBC News in a statement. "We want to again thank everyone for their tremendous amount of love and support during these last few months."

Bobbi Kristina was music royalty as the daughter of two superstars — and the granddaughter of another, Cissy Houston, the mother of Whitney, who died in February 2012.

Eya! RIP

So sad
