On Friday night’s Tonight Show Jimmy Fallon challenged Demi Lovato to a game of Wheel of Musical Impressions.

The way the game works is that the player is presented one singer and one song, typically a nursery rhyme or children’s song. The player then has to sing the song in the presented singer’s style.

She started off with her Cher impersonation with “Bingo Was His Name-O” and then did her best Fetty Wap bringing us a cover of “Twinkle Twinkle Little Star” to the tune of the rapper’s hit “My Way.” The real highlight though was Lovato’s Christina Aguilera impression which engendered wild applause as the ex-Disney delivered a spot-on impression, ad-libs and all, to the theme SpongeBob Squarepants theme song. At the end Fallon was on his chair cheering, “Oh my goodness! That was unbelievable!”

Fallon himself had some impressive impersonations of Louis Armstrong and Dave Matthews.
