Watch: Demi Lovato takes the absolute p*ss out of Nick Jonas in Carpool Karaoke
Poor old Nick.
Demi Lovato and Nick Jonas joined James Corden for the latest Carpool Karaoke. During the journey, Demi takes the opportunity to roast Nick over his on again off again relationships with Selena Gomez and Miley Cyrus.
To be fair to him he just sits in the back and takes all the slagging but puts an end to it eventually saying, "Are we going to keep talking about my dating life?"
As well as the obligatory singsong, James also asks them about intense fans and the weirdest things they've done.
