Rebel Wilson and Jimmy Fallon sang comical versions of holiday songs, revamped by Google Translate, during Tuesday night?s broadcast of The Tonight Show . The late-night host and Pitch Perfect 3 star had fun cycling lyrics through Google Translate, which transformed ?Deck the Halls? to ?The Homes Are Covered.? ?Yeah. Later Fallon sang ?Jingle Bells ? which was translated as, ?Bells Make Sounds.
