Demi Lovato left everyone speechless at the Tonight Show with her stunning impression of Christina Aguilera.

On Friday’s show, host Jimmy Fallon and the 23-year-old “Confident” singer played a round of “Wheel of Musical Impressions,” in which each competitor has to perform a song in the style of a randomly-selected popular singer.

While Lovato warmed up Cher singing “Bingo Was His Name-O” and surprised even herself with an impressive imitation of Fetty Wap crooning “Twinkle, Twinkle, Little Star,” it was her impersonation of Aguilera doing the “SpongeBob SquarePants” theme song that brought the house down.

Showing off her own powerhouse vocals, Lovato completely killed it, nailing Aguilera’s signature runs like an absolute pro. From the first note of her Aguilera mimic, it was clear Lovato had it in the bag -- and Fallon knew it.

“Oh my goodness! That is unbelievable! Game over! I can’t top that,” said a breathless Fallon, who was floored the second Lovato opened her mouth, in gracious defeat.

He sure can’t!

Lovato isn’t the only young pop star who’s dusted off their Aguilera imitation on the Tonight Show. Last September, Ariana Grande showed off her own impression of The Voice coach. All we need now is a face-off between Lovato, Grande and Aguilera herself for an epic showdown.

At the GRAMMYs earlier this week, Lovato left Lionel Richie speechless with her flawless cover of his 1980s ballad, “Hello.” Press play on the video below to relive the moment!
