Naomi Judd of Grammy-winning duo The Judds has died aged 76

Naomi Judd, the Kentucky-born singer of Grammy-winning duo The Judds and mother of Wynonna and Ashley Judd, died. She was 76.

The daughters announced their deaths in a statement to The Associated Press on Saturday.

“Today we sisters witnessed a tragedy. We lost our beautiful mother to the illness of a mental illness,” the statement said. “We are shaken. We navigate deep sorrow knowing that she was loved by her audience just as we loved her. We are in uncharted territory.” The statement was not elaborated on.

The Judds were scheduled to be inducted into the Country Music Hall of Fame on Sunday.

The mother-daughter performers scored 14 No. 1 songs in a career that spanned nearly three decades. After rising to the forefront of country music, they quit in 1991 after doctors diagnosed Naomi Judd with hepatitis.

The Judds’ hits included “Love Can Build a Bridge” (1990), “Mama He’s Crazy” (1984), “Why Not Me” (1984), “Turn It Loose” (1988), “Girls Night Out” ( 1985), “Rockin’ With The Rhythm Of The Rain” 1986 and “Grandpa” 1986.
