Watch Demi Lovato and Nick Jonas in Carpool Karaoke
Demi Lovato and Nick Jonas are the latest stars to join the Late Late Show host James Corden for a session of Carpool Karaoke. Jonas noted that the pair, who are about to embark on a summer concert tour, were celebrating their "tenth year of friendship this year." But, that was not enough to save him from being grilled about his dating history with Miley Cyrus and Selena Gomez, followed by Corden teasing Jonas about a purity ring that he used to wear. The trio also found the time to belt out Lovato's hit tunes Heart Attack and Cold Stone, Jonas' Close and Jealous and finally Cake By the Ocean by Joe Jonas' new band DNCE. Watch the full video above,
