Imitation is the sincerest form of flattery! Alicia Keys may be competing against Gwen Stefani on this season of The Voice, but on Tuesday night she took a moment to honor her pop rocker pal during the Tonight Show’s “Wheel of Musical Impressions” sketch.

The “Girl on Fire” singer, 36, jammed out to “Miss Mary Mack” as she tried to embody the No Doubt frontwoman.

Keys also tackled Adele while singing the “Alphabet Song,” in a rendition that prompted Fallon to declare, “I would buy that song tomorrow!”

But she really came into her own jamming out to Janis Joplin on “Twinkle, Twinkle, Little Star.”

For his part, host Jimmy Fallon also wowed as Elvis Presley on the “Meow Mix” jingle.

And though she slayed at the game, Keys admitted during her interview that her 6-year-old son, Egypt, is not impressed by her talents.

“He's at this age now where he wants to tell me that everybody's better than me. He'll be like, 'She kind of sings better than you, Mommy,'" Keys quipped.

Egypt does have some reason to brag. At the tender age of 5 he produced a track for rapper Kendrick Lamar, and Keys revealed, “He’s producing me!”

The singer’s one regret is that her son never met one of her late idols.

"He didn't know Prince. I would have loved for him to know Prince. That would have been so cool. [They] just kind of missed in the crossing," she said of the “Purple Rain” singer.
