Mariah Carey and James Corden reunite for a new Carpool Karaoke.
James Corden has released a brand new carpool karaoke video just in time for the holidays - featuring some surprise guests.
The video opens with Corden with his car loaded with Christmas presents, joined for the second time by Mariah Carey.
"What do you want for Christmas?" Corden asks.
"I don't know... I want you to sing my song," Carey replies coyly, before the two burst into a rendition of her Christmas smash hit All I Want for Christmas is You.
The video then reveals unseen footage from a number of Corden's other carpool karaoke specials, with him and a selection of musicians singing all to the song.

Adele, Selena Gomez, Lady Gaga, Elton John and Chris Martin are amongst the stars supercut together for one epic Christmas number.
While there are no new stories or revelations as has become common with Corden's videos, fans do get a quick shot of Carey blowing him a kiss as they sing "underneath the mistletoe".
It marks the final carpool karaoke of the year, which have dominated viral video lists around the world. Corden's video with Adele is the most watched late night clip of all time, and many of his other videos appeared in the top ten lists in New Zealand and globally.
Given that Carey's song, first released in 1994, has become a modern Christmas classic, selling more than 14 million copies worldwide, the two make the perfect holiday treat.
The Australian site cited a 'heightened threat level' as the issue.
