Tim McGraw has backed out of his scheduled performance at Sunday night’s 44th Annual Academy of Country Music Awards, Entertainment Weekly has confirmed.

A publicist for the country superstar tells EW that “due to a disagreement with show producers Tim’s manager has pulled him from the show.”

Reba McEntire will host the 2009 ACM’s, airing live on CBS at 8 p.m. ET/PT. Other entertainers slated to perform on tonight’s show include Miley Cyrus, Lady Antebellum, and Lee Ann Womack.
