NASHVILLE, Tenn. (AP) – Country music legend Loretta Lynn is postponing two shows in Iowa due to exhaustion.  A statement from Lynn’s representative on the singer’s website says Lynn “started feeling poorly midway through her three week tour” and is taking some time off to be treated for exhaustion. She said Lynn, who just finished a Canadian tour, is rescheduling both Iowa shows.

Last year, the singer postponed two shows to undergo more physical therapy following total knee replacement surgery. Lynn was born in the coalfields of eastern Kentucky and chronicled her life in an autobiography and song, both titled “Coal Miner’s Daughter.”
