Demi Lovato has a killer Fetty Wap impression

Demi Lovato is great at sounding like Demi Lovato. (You heard her sing during the Grammys, yes? Amazing. ) But she's also skilled at sounding like... Fetty Wap?

Fallon's Wheel of Musical Impressions gave us this gem of Lovato singing Twinkle Twinkle Little Star like Fetty Wap, and the Spongebob Squarepants theme as Christina Aguilera.

There's nothing wrong with being a confident impressionist!
