KNOXVILLE, Tenn. — In a concert Friday night in Knoxville, Tennessee, Lizzo filled the stage with drag queens in a glittery protest against the state’s legislation designed to restrict drag performances in public. While performing at Thompson-Boling Arena, the Grammy-winning “Juice” singer brought out a number of drag performers, including Aquaria, Kandy Muse, Asia O’Hara and Vanessa Vanji.
