Della Reese Deat at 86

Beloved singer and actress Della Reese, best known for starring in “Touched By an Angel,” died Sunday night … according to her family.

Della had battled diabetes for years. Her family says she passed away in her California home.

She co-starred with Roma Downey on ‘Angel’ … playing Tess. She had big movie roles too, like “Harlem Nights” and “A Thin Line Between Love and Hate” — and was the first black woman to guest host “The Tonight Show.”

Della was also an accomplished gospel singer — Mahalia Jackson discovered her. She went on to become an ordained minister in the 1980s.

Della was 86.
