VIDEO : Demi Lovato Plays the Wheel of Musical Impressions With Jimmy Fallon

Singer Demi Lovato showed off her musical impersonation chops on Jimmy Fallon?s Late Night Talk show Friday night. The pop star and reality TV judge happily played along with Jimmy for a few rounds of Wheel of Musical Impressions. Lovato did several impressions, including Cher singing ?Bingo Was His Name-O.? Jimmy was particularly impressed with the 23-year-old?s take of Fetty Wap singing ?Twinkle Twinkle Little Star.? But the former Disney Channel star really brought down the house with her rousing version of Christina Aguilera singing ?Spongebob Squarepants.?
