Country stars Luke Bryan and Zac Brown ended their feud with an embrace at the 47th annual CMA Awards in Nashville, Tennessee on Wednesday night (06Nov13).

As event co-hosts Brad Paisley and Carrie Underwood urged warring country stars to get along by singing War's Why Can't We Be Friends, Bryan and Brown met in the audience at the Bridgestone Arena for a hug.

The two stars fell out when Brown went public with his dislike for Bryan's hit My Kinda Night, which he opened the show with.

The Zac Brown Band frontman called the single the "worst song" he's ever heard, adding it makes him want to "throw up" every time he hears it.

Justin Moore and Jason Aldean both jumped to Bryan's defence, but the singer himself opted not to fight back.

Paisley and Underwood, who are co-hosting the ceremony for the sixth time, also poked fun at feuds between Kanye West and comedian Jimmy Kimmel and the Jonas Brothers as part of their impromptu acoustic performance at the top of the show, and then called on singer Kellie Pickler to hand out "feuding assignments" to stars like newlywed Kelly Clarkson, who was urged to start a fight with her real-life mother-in-law Reba MCEntire, with Paisley joking, "That was bound to happen eventually!" - and Kenny Rogers, who was picked to feud with the Celebrity singer onstage.

Paisley stopped singing and hurled joke insults at the Coward of the County singer, stating, "Kenny Rogers is pure evil!"
