Singers John Legend and Meghan Trainor, actor Josh Gad and Scandal star Bellamy Young "auditioned" for comedienne Ellen DeGeneres on her U.S. chat show on Wednesday (14Oct15), as she sat in a spinning red chair just like the one judges on TV talent show The Voice use. Each star sang a tune as the host attempted to guess who was behind her. Meghan disguised her voice while singing T-Pain's Buy U Drank while Legend covered Taylor Swift's Shake It Off.
