The American Music Awards celebrate all genres of music, and some of country's biggest stars played big roles in the 2015 ceremony, held in Los Angeles on Sunday night (Nov. 22).

Carrie Underwood stunned with the television debut of her new song "Heartbeat," while Luke Bryan and Little Big Town's Karen Fairchild heated things up with their duet "Home Alone Tonight," but they weren't the only country artists in the spotlight. Kelsea Ballerini and Florida Georgia Line presented a trophy to Bryan, one of the evening's many country nominees, while Sam Hunt earned a much-deserved (and surprising) win in the all-genre New Artist of the Year category.
