Selena Gomez Slays This Star-Studded X-Mas 'Carpool Karaoke' With James Corden

If you've been tuning into to “The Late Late Show with James Corden," you may have gotten a glimpse of the early Christmas present Corden gave to the world during his latest installment of “Carpool Karaoke."

If you missed his latest ride, let me fill you in.

Corden piled a bunch of presents into the back seat of his SUV and picked up the infamous Mariah Carey who was looking festive AF in a red cleavage-baring ensemble.

As they drove around LA, Corden asked Mariah about what she wanted for Christmas this year.

Naturally, Mariah told Corden she wanted him to sing her signature holiday song, "All I Want For Christmas Is You."

As the two belt out Mariah's melody, Corden sudden hits us with a big surprise: a star-studded, holiday-themed "Carpool Karaoke" mashup that's simply glorious, to say the least.

That's right. The screen cuts away from Mariah and starts showing clips of Corden singing "All I Want For Christmas Is You" with previous passengers who appeared on the show throughout the year.

Corden recruited all sorts of celebs for the surprise like Selena Gomez, Adele, Lady Gaga, Gwen Stefani, Demi Lovato, Nick Jonas and Chris Martin.

He even got legendary artists like Elton John and The Red Hot Chili Peppers to join in on the festive fun.

Yep, it's not hard to see Corden really planned out this epic Christmas present in advance.

Unfortunately, a few carpool guests like Madonna, Jennifer Lopez, Justin Bieber and Britney Spears were missing from the year's holiday lineup.

But the stars who did participate in Corden's adorable surprise totally nailed it.

I'm not kidding. If you thought the winter weather gave you some serious chills, just wait until you hear all of these talented singers hit the high note at the end of this classic Christmas song. Happy Holidays!
