James Corden’s Carpool Karaokes have been a blast, and today’s Nick Jonas/Demi Lovato double-act was no exception.

Nick Jonas and Demi Lovato are celebrating their 10-year friendship this year! Isn’t that nice?

James Corden opens with some awkward small talk about who dated who. To sum up: Cyrus, Gomez, Cyrus, Gomez, and something about when that purity ring came off.

And then they start singing.

James Corden kills those high notes on the first one — and it’s especially nice when Nick Jonas knows the lyrics.

In the song break, Nick recalls a crazy fan story, and they talk some more about the purity rings. All you Jonas Brothers fans, we hope you’re paying attention.

If nothing else, after this video, we’re pretty much convinced Demi and James are gonna be best friends.

Nick Jonas and Demi Lovato are heading out on a big concert tour dubbed “Future Now” in June, their first show on June 29 in Atlanta, rounding out on September 17 in Los Angeles.

Previous Carpool Karaokes with James Corden include the unforgettable Adele, One Direction and Mariah Carey performances.

They are arguably what really cemented Corden’s success as a late show host, with his most recent video (Adele) getting over one hundred million (!) views.

We can’t wait to see who else he brings into the car with him… and really hope he’s driving down deserted streets, as those hand movements really get away from him sometimes!
