Every single time James Corden delivers another "Carpool Karaoke" session on the Late Late Show, it makes our day. It all started with an epic Mariah Carey singalong in March 2015, and since then, we've fallen back in love with Justin Bieber and even cried because of Stevie Wonder. More recently, James has really upped the ante with Ed Sheeran, who told a hilarious story about smacking Justin Bieber in the face with a golf club, Pink, who never fails to put on an amazing show, and Harry Styles, who showed off his knowledge of Titanic. To keep the joy coming, we've collected all of the installments that have happened so far. Check them out!
