Leann Rimes cut short a show in Oklahoma on Saturday night (22Mar14) after an ongoing jaw condition flared up.

The singer has revealed she is suffering from a temporomandibular joint disorder (Tmj) which causes a painful jaw and restricted movement, and she battled through the agony at her show in Durant, Oklahoma.

Rimes decided to skip her encore and shorten the show due to her health problems, and later apologised to fans in a post on Twitter.com, writing, "Oklahoma!!!! I love you so much! I'm sorry for no encore. I had my jaw pop out of place & I can't hear out of my left ear... Tmj sucks."
