Watch: Ariana Grande, Kelly Clarkson deliver jaw-dropping covers of Britney Spears, Celine Dion, Whitney Houston, more

There is nothing in this world Ariana Grande and Kelly Clarkson can't sing.

The first episode of NBC's new comedic music game show "That's My Jam," hosted by Jimmy Fallon, aired Monday, and one segment called "Mixtape Medley" pitted Clarkson and Grande against each other in a competition to see who can cover "all-time classic diva tracks" better. 

Among the songs selected were "Oops!... I Did It Again" by Britney Spears, "Believe" by Cher, "You Oughta Know" by Alanis Morissette, "How Will I Know" by Whitney Houston, "I Will Always Love You" by Houston, and "It's All Coming Back To Me Now" by Celine Dion.

It's impossible to choose a winner. Watch for yourself:

Ultimately, though, Clarkson and her teammate John Legend were crowned winners of this game as well as "Slay It Don't Spray It":

Grande was teamed up with Blake Shelton. The four stars serve as coaches on NBC's "The Voice," which is currently airing its 21st season on NBC through Dec. 14.

"That's My Jam" is a spinoff of "The Tonight Show Starring Jimmy Fallon" and will air its official series premiere Monday, Jan. 3, beginning at 9:00 p.m. EST on NBC.
