Loretta Lynn cancels shows, cites exhaustion

Country music legend Loretta Lynn is postponing two shows in Iowa because of exhaustion.

Lynn's rep said the 81-year-old singerstarted feeling poorly midway through her three-week tour and is taking some time off to be treated. The statement revealed, "Lynn started feeling poorly midway through her three week tour. Loretta is a pro and wants to give her fans the best show possible. She felt she physically was unable to do that."

The statement says Lynn, who just finished a Canadian tour, is rescheduling both Iowa shows.

Last year, the singer postponed two shows to undergo more physical therapy followingtotal knee replacement surgery. In 2011, she was hospitalized with pneumonia.

Lynn was born in the coalfields of eastern Kentucky and chronicled her life in an autobiography and song, both titled "Coal Miner's Daughter."
