Country music icon Loretta Lynn is mourning the loss of her daughter, who died on Monday morning (29Jul13).

Betty Sue Lynn passed away from complications related to emphysema. She was 64.

It's the second time the Coal Miner's Daughter singer has had to say goodbye to one of her children - her son Jack Benny Lynn drowned in 1984 when he was 34.

The country music legend's husband of 48 years, Doolittle Lynn, lost his battle with diabetes in 1996.

Loretta Lynn 'died' on the operating table in 2006, but lived to fight another day.
