So this is what the kids are listening to these days!
Even if you have never, ever heard a song by Demi Lovato or Nick Jonas, you will fall a little bit in love with them after watching the latest Carpool Karaoke with James Corden.
The pair have been friends since their Disney days... 10 whole years ago. (Yes - they are young. Both 23, in fact.)
They are so close they can even joke about Nick's long list of famous girlfriends, including Miley Cyrus, Selena Gomez, Gigi Hadid and even Aussie Delta Goodrem.
Demi's list is remarkably shorter, but it does include Nick's brother Joe and her current boyfriend of six years, Wilmer Valderrama.
In their Carpool Karaoke segment, Demi and Nick sing some sweet harmonies and even take a turn at busking on the street - and, boy, does Demi have some pipes!
