There's No Third Wheel When Demi Lovato And Nick Jonas Do Carpool Karaoke With James Corden

James really wants to go on tour with them.

Last night on The Late Late Show, host James Corden debuted yet another installment of Carpool Karaoke, and it doesn't look like this segment will be getting old anytime soon. This time, his famous passengers were Demi Lovato and Nick Jonas. Demi and Nick are going on tour together next month, and James is determined to convince them he should join. He makes a pretty good case for himself, as you'll see.

It doesn't take long for the three of them to prove they've got great harmony, as they belt out to hits by both Demi and Nick. That includes Demi's "Heart Attack" and Nick's "Chains." They even rock out to "Cake By the Ocean" by Joe Jonas' group DNCE.

James eventually says what we're all thinking and suggests that the three of them become an act. He even has a band name at the ready — James Corden, borrowing letters from each of their names. So maybe that needs some work, but there's no denying he's got the talent. 

Demi and Nick decide to put James to the test by having him perform a show with them. This leads them to getting out of the car and turning into street performers, bucket drums and all. 

The crowd seems to love their rendition of Demi's "Confident," but in the end Demi and Nick decide to remain a twosome. The good news is, that means James is free to continue bringing us even more delightful Carpool Karaoke segments in the future.
