Chappell Roan brought laughs — and a little shock — to the Rock & Roll Hall of Fame Induction Ceremony on Saturday when she accidentally dropped an F-bomb while introducing Cyndi Lauper. Roan was delivering a heartfelt tribute to Lauper, praising her authenticity and influence, when she stumbled over the teleprompter and blurted out, “I f—,” before covering her mouth. The crowd erupted in laughter as Roan joked, “I messed up so bad by refusing to get contacts. Holy cow.” Once she recovered, Roan went on to deliver a moving introduction, calling Lauper “a music legend whose authenticity has inspired us for four decades.” Dressed in a replica of Lauper’s True Colors music video outfit, Roan helped usher the pop icon onstage for a performance of her biggest hits — including “Girls Just Wanna Have Fun,” “Time After Time,” and “True Colors” — joined by Avril Lavigne and Salt-n-Pepa.
