James Corden is a multitalented performer, but it's his performances in Carpool Karaoke that first made him a huge star in America and an obvious choice to host the 2017 GRAMMY Awards.
He joked that CBS contractually made him wear a cardboard Carpool Karaoke cutout to ensure people would know him and ended up using the car to stage the most star-packed Carpool Karaoke ever.
After convincing huge musicians Jennifer Lopez, Jason Derulo, John Legend, Keith Urban, Neil Diamond, and many more "to get in," he got them all to sing a rendition of "Sweet Caroline" like none other. Even Blue Ivy joined the party toward the end.
