In her hit song “Confident,” Demi Lovato urges women to be themselves.

Lovato appeared on Friday’s episode of “The Tonight Show” for a spin at Jimmy Fallon’s Wheel of Musical Impressions.

The next round threw her a curveball: Fetty Wap, singing “Twinkle, Twinkle, Little Star.” Huh? Fetty’s barely been around long enough to have impersonators, but Demi’s performance of “Twinkle” crossed with the hip-hop star’s “My Way” is spot on.

Fetty, if you decide to cover this one, we hope you’ll give Demi some credit.

Finally, Lovato gets to show off her powerful pipes as riff queen Christina Aguilera performing the “Sponge Bob Square Pants” theme.

That pineapple under the sea has some killer acoustics.
