WATCH: Jonas Brothers Take Lie Detector Tests During "Carpool Karaoke"

March 8, 2019

The recently reunited Jonas Brothers go through the ringer while taking a lie detector test in the latest “Carpool Karaoke” segment. During the test, Joe admits that Kevin gets on his nerves the most and Kevin reveals that Nick’s multi-day wedding celebration was a bit long. For what its worth, Nick also says he was ready for his wedding to be over when he “saw the bill”--but lies when he claims he’s not a better singer than his brothers. Joe also gets caught in lie when he says his brothers’ wives never get on his nerves. The fellas also discuss the purity ring drama they dealt with as teens (Kevin took his off first)--and sing hits such as “When you Look Me in the Eyes,” “Lovebug” and “Sucker.”
