“I’m thrilled to come back to Nashville to co-host the CMT Music Awards,” Andrews says in a statement. “I had so much fun last year, and I can’t wait to see what antics JJ and I will get into together."

Adds Watt, "There are two things that I know about the people of Nashville: They love country music, and they know how to throw a party. When you put those two things together, it makes for one heck of a night."

A few presenters for the 2016 CMT Music Awards were also revealed: actors Vince Vaughn, Rob Riggle, Joey Lauren Adams and Madison Iseman; NASCAR driver Danica Patrick; and country stars Charles Kelley, Cole Swindell, Dan + Shay and Kellie Pickler.
