"It is hard to say goodbye," the message, which was posted to Whitney Houston's official Facebook page, read. "On Sunday, July 26, Bobbi Kristina Brown made her transition peacefully. The family thanks everyone for their loving thoughts and prayers."
Houston's cousin, Dionne Warwick, also released a statement to ET. "Our family has had its share of sorrow these past few years and it is with a heavy heart that I have to once again say so long to a loved one," she said on Monday. "Bobbi is now sitting in the lap of our Heavenly Father and is now reunited with her beloved mother. She will be missed and I send many thanks for all of the prayers that were being said for her."
Brown was found unresponsive in her bathtub on Jan. 31, 2015, 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 center, where she remained until June 24, when she was moved to the hospice center where she died on Sunday.
