Jennifer Aniston announced the death of her mother on Wednesday evening. "It is with great sadness that my brother John and I announce the passing of our Mother Nancy Dow," she told People in a statement. "She was 79 years old and passed peacefully surrounded by family and friends after enduring a long illness. We ask that our family’s privacy be respected as we grieve our loss."

They split when the Friends star was nine.
