Loretta Lynn is re-scheduling some upcoming shows due to exhaustion. The 81-year-old country legend revealed the news through a representative on Tuesday (Oct. 29).

“Lynn started feeling poorly midway through her three week tour," her rep said in a post to her website. "Loretta is a pro and wants to give her fans the best show possible. She felt she physically was unable to do that."

On the heels of a grueling Canadian tour, the veteran entertainer is taking some time off to seek treatment for exhaustion, postponing two shows in Iowa that she will re-schedule at a later date.

Lynn also postponed some concerts last year to undergo more physical therapy after a knee replacement, and in September she was forced to cancel some shows after being injured in an accident at her home.

The country icon will need her strength for a very special trip she has coming up. She is among the 16 recipients announced for the 2013 Presidential Medal of Freedom, which is America's highest civilian honor. She will receive the medal at a ceremony on Nov. 20 alongside this year’s other honorees, who include Oprah Winfrey, President Bill Clinton and Chicago Cubs legend Ernie Banks.
