0508_cooper_singleJeanne Cooper -- who played Katherine Chancellor on the soap opera "The Young & The Restless" for nearly four decades -- died today at age 84.

One of the grand dames of daytime television, Jeanne was nominated for a Daytime Emmy 11 times and won Best Actress in 2008. One of her most memorable moments came in 1984, when Jeanne and her character underwent a face-lift at the same time.

Jeanne had been hospitalized since April due to an undisclosed illness.

Her son, actor Corbin Bernsen, shared the news of her passing, tweeting: "Mom passed this morning. She was in peace and without fear. U all have been incredible in your love. In her name share it 2 day with others."

CBS Entertainment president Nina Tassler remembered the veteran actress as "a daytime television legend and as a friend who will truly be missed by all of us here at the network."
