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 sing-along back in March 2015, and things came full circle this week when Mariah returned (alongside a whole host of other stars) for a Christmas sing-along. Over the last couple of years, we've fallen back in love with Justin Bieber and even cried because of Stevie Wonder. Then came Adele, who took things to a whole new level. To keep the joy coming, we've collected all of the instalments that have happened so far. Check them out ahead!
