Country star Tim McGraw pulled out of performing at the star studded Academy of Country Music Awards just hours before the show after a furious alleged fight with the event's producers over his set. The famed singer was scheduled to take the stage at the Las Vegas Nevada event on Sunday but reportedly stormed out of the rehearsals the previous day over a dispute about his production design. His publicist has not addressed the cause of the argument but confirms McGraw withdrew due to a "major disagreement" with television bosses.
