On Sunday night (6/11) in Houston, singer Faith Hill [ tickets ] made a surprise appearance at the sold-out final stop of the George Strait [ tickets ] Country Music Festival.

Dressed as a Houston police officer, Hill led her husband Tim McGraw [ tickets ] off of the stage in handcuffs at the end of his performance--earlier this month, McGraw and tourmate Kenny Chesney [ tickets ] were arrested following a previous festival stop in Buffalo, N.Y.

The festival played in 10 cities to a total of nearly half a million people, according to the tour promoter.

Other performers on the tour included Mark Chesnutt, Martina McBride, Lee Ann Womack and Asleep at the Wheel.
