Lovato has experience singing the "Star-Spangled Banner" before a big sports event. In 2015, she performed the national anthem ahead of Game 4 of the World Series between the New York Mets and Kansas City Royals. She also sang the national anthem during Game 5 of the 2011 World Series and before a 2008 Dallas Cowboys game.
