WATCH: Alicia Keys covers Adele, Gwen Stefani at Fallon’s show

Alicia Keys stopped by “Tonight Show Starring Jimmy Fallon” to blow away each and everyone with her impersonations of some artists.

On Tuesday, the “Girl on Fire” hitmaker appeared in the show’s star-studded segment “Wheel of Musical Impressions,” a game where a guest impersonates a singer while singing a nursery rhyme.

For the first part, Keys was challenged to mimic fellow “The Voice” judge Gwen Stefani while chanting “Miss Mary Mack.”  She replaced the lyrics of Stefani’s “Hollaback Girl” with the jingle.

But netizens were left gasping for air when Keys, a powerful chanteuse, belted out “The Alphabet Song” like how Adele might have done it, using the tune of her Grammy-winning hit, “Hello.”

Not only did Keys, 36, nail her Adele impression—she wrapped up the skit by mimicking Janis Joplin’s husky voice for “Twinkle, twinkle, little star” with the rock melody of Joplin’s “Piece of My Heart.”

During her guesting, Keys revealed how she sought permission from the late singer Prince to cover his 1982 song “How Come U Don’t Call Anymore” for her debut album, “Songs in A Minor.”

“I didn’t know you had to ask permission so there’s this whole big ordeal and I had to call him,” she explained to host Jimmy Fallon.  Gianna Francesca Catolico /ra
