LeAnn Rimes reveals to fans that she experienced ‘utter embarrassment’ after her fake teeth popped out of her mouth mid-concert on Friday in Washington. The singer ran off stage in the middle of her performance of ‘One Way Ticket’ to put them back in. LeAnn is currently on tour through the end of November; and she’s joining the cast of the new spin-off ‘911: Nashville,’ with Chris O’Donnell, Jessica Capshaw and Kimberly Williams-Paisley. The Ryan Murphy series premieres this fall on ABC.
