Shawn Mendes is the latest singer to join James Corden for Carpool Karaoke (following in the footsteps of the likes of Kelly Clarkson [1], Pink [2] and Christina Aguilera [3] in the karaoke hall of fame). In the latest skit, the pair have a chat about Shawn's deep love of Harry Potter [4], discuss how Shawn has moved into his own place (though his mom still does his laundry), and they even get out of the car to have a skate on the ice. Spoiler: it turns out that James Corden is not great at ice hockey! Of course, they have had time to belt out a few big hits, too. Our favorite part? When Shawn admits exactly how much he would pay for a pair of Justin Bieber's underwear. Whatever you want to spend your money on, Shawn! We're not here to judge.

Watch Shawn and James have a sing-along and then catch up on even more Carpool Karaoke videos [5] here.
