Kitty, who was born Ellen Muriel Deason, was the first woman to reach Number One on the country charts with her 1952 hit, "It Wasn't God Who Made Honky Tonk Angels." It held the top spot for six weeks and was the first of 33 Top 10 hits for Kitty through 1965.
She was inducted into the Country Music Hall of Fame in 1976, and she received a 1991 Lifetime Achievement Award from the Recording Academy.
Kitty's husband and fellow singer, Johnny Wright, died in 2011. They had been married since 1937.
Fellow country singers remembered Kitty, issuing statements and posting their thoughts on Twitter yesterday.
Barbara Mandrell said, "Kitty Wells was every female country music performer's heroine. She lead the way for all of us and I feel very grateful and honored to have known her. She was always the most gracious, kind and lovely person to be around. I so appreciated her being a part of my life and a mentor to me."
Loretta Lynn said, "Kitty Wells will always be the greatest female country singer of all times. She was my hero. If I had never heard of Kitty Wells, I don't think I would have been a singer myself. I wanted to sound just like her, but as far as I am concerned, no one will ever be as great as Kitty Wells. She truly is the Queen of Country Music."
Martina McBride tweeted, "Sad to hear of the passing of the Queen of Country, Kitty Wells."
Sunny Sweeney tweeted, "Deeply saddened to hear of the passing of country music pioneer and Honky Tonk Angel, Kitty Wells. She was a hero to every female singer. <3"
Kellie Pickler tweeted, "My heart cries over the loss of Ms Kitty Wells. She is and always will be the true Queen of Country Music."
