Jimmy Fallon debuted a new Lip Sync Battle on Monday's Tonight Show, with a guest who wasn't afraid to go all in with her performances: Melissa McCarthy.
While Fallon performed perfectly respectable renditions of Melanie's "Brand New Key" and Zayn Malik's first solo single, "Pillowtalk," it was The Boss star who stole the show with DMX's "X Gon' Give It to Ya" and an epic, interactive performance of the Disney classic, "Colors of the Wind," from Pocahontas.
Fans may have been perplexed when the actress donned safety goggles at the top of the song, but the confusion didn't last long, as the elements named in the song -- stuffed animals, feathers and water -- began flying at McCarthy as she sang them, courtesy of a high-powered wind machine.
The actress ended her number to a standing ovation, totally covered in confetti, streamers and fake leaves. So, of course, she gave Fallon a massive hug.
