Ariana Grande and Kelly Clarkson's karaoke showdown

Power belters Ariana Grande and Kelly Clarkson proved their vocal prowess yet again as they went mic-to-mic and it gave viewers the goosebumps.

In American tv host Jimmy Fallon's That's My Jam, an hour long music and comedy variety show, the two were challenged to a "Mixtape medley" showdown. This means they would give their own rendition of some all-time classics of iconic pop divas in history like Britney Spears, Celine Dion, Whitney Houston, Shania Twain, and Cher.

In this episode, John Legend and Kelly are teammates going against Ariana and Blake Shelton.

Ariana opened it with her squeaky version of Britney's "Oops I did it again." Kelly answered back with her fiery version of Shanaia's "Any Man of Mine."

Ariana then raised the game and showed off her big voice to give justice to Cher's pop classic "Believe."

Audiences then went wild as the American Idol diva shot back with her powerful take on one of the '90s most jammed pop anthems, "Oughta Know" by Alanis Morissette.

The "Thank You Next" hit maker electrified the audience with her version of Whitney's disco hit "How Will I Know."

The "Since You've Been Gone" singer then set the concert stage as she belted Toni Braxton's "Unbreak My Heart."

This time, as the audience hold in their breaths, the two stretch their lungs out for some '90s divas classics.

Ariana continued on the power belter mood when she gave her all for Celine's "It's All Coming Back To Me."

Kelly finally killed the battle when she showed how Whitney's "I Will Always Love You" should be done.

Jimmy could not contain his awe over the two singers as seen in his reaction after their vocal battle.

Kelly and John turned out to be the winners.
