James Corden hosted the Grammy Awards and included a special version of "Carpool Karaoke," albeit in a cardboard cutout vehicle inside the Staples Center. The sing-along version of Neil Diamond's classic "Sweet Caroline" included stars such as Diamond, Jennifer Lopez, Jason Derulo, John Legend, and Keith Urban, with Beyoncé and Jay Z's daughter Blue Ivy crashing the party.

James Corden Had Denied Grammy 'Carpool Karaoke' Appearance

When we last reported on James Corden's then-upcoming Grammy hosting appearance, the big question was whether the late-night chat show host of The Late Late Show With James Corden would somehow be incorporating his most popular segment from the show, "Carpool Karaoke," into the Grammys. After all, it was the musical sing-along car rides that most likely landed Corden the gig hosting the music industry's biggest awards show, but in a pre-show interview, Corden dismissed the possibility of a "Carpool" segment on the Grammys, citing time constraints.

Despite his denial, we told you that there was still a good chance Corden would find a way to work a version of "Carpool Karaoke" into the show and that it was likely if he had such a surprise up his sleeve, he wouldn't reveal it to potential Grammy watchers in advance.

Corden Joined By Jennifer Lopez, Neil Diamond, John Legend, Blue Ivy, And More

Sure enough, Corden managed to figure out a clever way to host a brief "Carpool Karaoke" sing-along during the Grammys. Corden appeared in the audience wearing a cardboard cutout of a car and joked that CBS had contractually required him to wear it due to the popularity of "Carpool Karaoke." He then ran up to where Jennifer Lopez was seated and framed her into the passenger seat of his makeshift vehicle.

After a brief chitchat with JLo, Corden then brought over a group of singing stars such as Jason Derulo, John Legend, Keith Urban, and Neil Diamond to sing an impromptu version of Diamond's classic "Sweet Caroline," inviting the entire Grammy audience to join in. It's a good thing they did because clearly many of Corden's car "passengers" had no idea what the words to the song were. The moment was lifted, however, when Blue Ivy, celebrity spawn of Jay Z and Beyoncé, escaped her assigned seat by her famous parents and ran over to join in on all the fun. While that moment was clearly spontaneous, it was no coincidence that the commercial for the new Apple Music version of "Carpool Karaoke" aired directly afterward.
