Shawn Mendes is the latest singer to join James Corden for Carpool Karaoke (following in the footsteps of the likes of Kelly Clarkson, Pink and Christina Aguilera in the karaoke hall of fame). In the latest skit, the pair have a chat about Shawn's deep love of Harry Potter, discuss how Shawn has moved into his own place (though his mum 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 favourite 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.
