Demi Lovato appeared as a guest on The Tonight Show with Jimmy Fallon. 

The two played a game of Wheel of Musical Impressions. Lovato hit it big with her Cher impersonation, singing “Bingo Was His Name-O," followed by her spot-on rendition of “Twinkle Twinkle Little Star” in Fetty Wap’s distinctive, drawn-out vocal style.

The pop star’s finale was the SpongeBob Squarepants theme song as sung by Christina Aguilera, which was a major crowd-pleaser. Fallon had little luck with his Dave Matthews impersonation but was successful when he sang “Mr. Rogers Neighborhood” in the voice of Louis Armstrong.
