While no one holds a candle to Carey's rendition of "All I Want for Christmas Is You," Corden's super cut of previous segments might just bring this classic tune to the next level. Who doesn't love finding out that Adele, Selena Gomez, Demi Lovato, Nick Jonas, Elton John and more planned ahead and secretly recorded Carey's hit?!
But, like any Carpool Karaoke, if you pay close attention you'll notice things you might have otherwise missed. Here are five things you didn't notice:
1. It might just have been the editing, but it appeared that Gwen Stefani didn't really know the lyrics except for the chorus. She often leaves Corden to do the singing while she bounces along to the beat.
2. Because Adele's original segment taped in England, Corden's driver's seat was on the other side of the car! But no matter where Corden and co. film, he always drives the same type of car: Range Rover.
3. Corden was wearing the same blue polo in both Gomez's and Lady Gaga's Carpool Karaoke segments. (To be fair, the British host often makes fun of his wardrobe).
4. Before launching into song at the beginning of the Christmas segment, Carey briefly adjusted her earpiece—who even knew they wore earpieces?!
5. When Adele sings, fans typically can't hear her British accent, but while belting out "All I Want for Christmas Is You," her accent was incredibly clear.
