A spokesperson for the family said Saturday that the service will be at West Angeles Church of God in Christ, where Cole was once a member. R&B star Chaka Khan is expected to sing at the funeral.
Cole will be buried next to her parents, sister and brother at Forest Lawn Memorial Park in Glendale.
She was known for such R&B hits as "This Will Be (An Everlasting Love)," ''Inseparable," and "Our Love." In 1991, she intertwined her musical legacy with that of her father Nat King Cole to make his "Unforgettable" a Grammy-winning hit through technological wizardry.
