LAS VEGAS (AP) — More than a few people have suggested to the producers of the Academy of Country Music Awards that they extend the broadcast delay for Sunday night's show — just in case.

With Blake Shelton and Luke Bryan co-hosting the show, everyone expects the unexpected — and several off-color, unscripted moments — as country music's biggest cut-ups collide. In a recent interview in Nashville, the two gave themselves the celebrity couple name "Bluke" and made off-color jokes.

The 48th annual awards show kicks off at 8 p.m. EDT live on CBS from the MGM Grand in Las Vegas. The night will be a showcase for country's men of the moment, and for its two dominant male stars of the last two decades — Garth Brooks and George Strait.
