LOS ANGELES (Reuters) – Cissy Houston, Grammy-winning soul and gospel singer and mother of the late Whitney Houston, died on Monday at the age of 91 at her home in New Jersey.

Houston’s daughter-in-law, Pat Houston, shared the news on Instagram.

“It saddens my heart to announce the passing of my beloved Queen Cissy Houston today! Please keep the Houston family in your prayers,” Pat Houston wrote alongside a photo collage of the late singer.

The gospel singer was born in Newark, New Jersey, as Emily Drinkard on September 30, 1933, and later adopted the professional name Cissy Houston.

She began her career as a member of a gospel group called the Drinkard Four and later became a founding member of the R&B group Sweet Inspirations.

She sang backup for legendary artists such as Aretha Franklin, Chaka Khan, Otis Redding and Dionne Warwick.

Her music defied gender and racial boundaries, and she collaborated with Elvis Presley, Bette Midler and Linda Ronstadt – a rare feat for a black artist at the time.

Houston launched her solo career in 1970 and won two Grammy Awards for her gospel music.

Cissy Houston’s daughter, singer Whitney Houston, died in 2012 at the Beverly Hilton hotel. She was found submerged in her bathtub by a member of her personal staff.
