Guess we know what artist Demi Lovato picks on karaoke nights! Appearing on The Tonight Show with Jimmy Fallon, she did a spot-on impression of Christina Aguilera – signature vibratos and all – singing the Spongebob Squarepants theme.

Lovato also nailed her impressions of Cher and Fetty Wap in the “Wheel of Musical Impressions” game. But it was her channelling of Aguilera that killed. Fallon was so pumped up he jumped out of his chair, saying “game over.”
