“On behalf of her husband, Franklin Lett, and all her friends and family, I share with you the news that our beloved Della Reese has passed away peacefully at her California home last evening surrounded by love. She was an incredible wife, mother, grandmother, friend, and pastor, as well as an award-winning actress and singer.

her costar Roma Downey confirmed to PEOPLE in an exclusive statement.

“She was a mother to me and I had the privilege of working with her side by side for so many years on Touched By an Angel. I know heaven has a brand new angel this day. Della Reese will be forever in our hearts. Rest in peace, sweet angel. We love you.”

“We’re deeply saddened to learn of the passing of Della Reese,” CBS tells PEOPLE in a statement: She was a multi-talented, award-winning performer who shined brightly on soundstages and in concert halls. For nine years, we were privileged to have Della as part of the CBS family when she delivered encouragement and optimism to millions of viewers as Tess on Touched By an Angel.

Born Delloreese Patricia Early on July 6, 1931 in Detroit’s Black Bottom neighborhood, Reese began singing in public at just 6 years old at her local church, establishing her roots in gospel music. Her vocal talent flourished and by 13 she was tapped to perform with Mahalia Jackson’s gospel group, with whom she’d later tour.
