Kelly Clarkson and Ariana Grande Sing Iconic Divas' Songs on 'The Tonight Show,' and Viewers Can't Contain Themselves

It's safe to say that Ariana Grande and Kelly Clarkson are two of the biggest pop stars on the planet. However, instead of singing their own hits during their recent appearance on The Tonight Show Starring Jimmy Fallon, they tried their hands at some classic pop diva tracks. Judging by the social media responses to the pair's performance, fans couldn't get enough of Grande and Clarkson's "Mixtape Medley Showdown."

Clarkson and Grande appeared alongside their fellow coaches from The Voice, Blake Shelton and John Legend, in order to promote the NBC series. Even though they all appeared on the show, it was up to Grande and Clarkson to battle it out. This wasn't just any regular singing battle, though. The "Mixtape Medley Showdown" involved the singers performing widely celebrated tracks such as Britney Spears' "Oops... I Did it Again" and Whitney Houston's "I Will Always Love You." Unsurprisingly, they both brought down the house by the end of the segment. 

Fans were blown away by Grande and Clarkson's powerful "showdown." They didn't waste any time in taking to Twitter to hype up that very performance.
