Alicia Keys Did A Flawless Adele Impression On 'The Tonight Show' And We Are SHOOK

Jimmy Fallon learned a valuable lesson on Tuesday night's Tonight Show: Never challenge Alicia Keys to a game of "Wheel of Musical Impressions." You will lose.

First, the 36-year-old singer was tasked with embracing her inner Gwen Stefani while singing "Miss Mary Mack," and it was pretty damn good — especially when she gave it a little "Hollaback Girl" edge.

Bonus points for those dance moves.

But the moment Keys flat-out stunned us was when she did an impression of Adele singing "The Alphabet Song." Like, are we sure the woman in front of us isn't *actually* Adele dressed up as Alicia Keys? Someone get the FBI on the line — we might need to investigate a serious case of identity theft.

Sorry, Jimmy — you're taking an L this round. Keys didn't even need to slay her Janis Joplin-esque cover of "Twinkle Twinkle Little Star" after that. (Obviously, she did anyway, but that's besides the point.)
