Those “purity rings” from back in the day also piqued Corden’s curiosity. Regardless, Lovato and Jonas placed their child star days firmly in the past, and proved it with some stellar singing in Corden’s car. During the skit, they performed Demi’s “Heart Attack” and Nick’s “Chains.”

“Stone Cold” from Lovato’s Confident album made a second appearance on Corden’s show. During her last appearance she sang it for the late night funnyman in a stranger’s dining room. In addition to providing tweet-worthy tidbits, the two pop stars demonstrated their genuine chemistry.
