Carpool Karaoke's star-studded 'All I Want For Christmas' is everything we ever wanted.

On Friday, The Late Late Show with James Corden released their Carpool Karaoke with Bruno Mars and people were fast in asserting that this was the best clip Corden had done.

And that, in hindsight, is no small feat. Corden has had an Obama in his car, as well as a Clooney, a Lopez and a Bieber.

But everyone was perhaps a little over-excited. Because don’t we all know the term, ‘saving the best for last’? Why hadn’t we considered that Mimi and All I Want For Christmas was the obvious choice to overhaul the trauma that was 2016 in all its Brexit-y, Trump glory?

In Corden’s latest clip, the duo smash out the cult Christmas hit together, giving us the early Christmas present we never thought we needed.

Even better? This one has been a LONG time in the works. The TV host pre-prepared the Christmas special throughout the year with the likes of his guests Adele, Elton John, Lady Gaga, Demi Lovato, Nick Jonas, Chris Martin, Selena Gomez, Gwen Stefani and the Red Hot Chili Peppers.

And it looks like they’re all having the time of their lives, even if most of them can’t quite hit the song’s famous high note – even, dare we say it, Adele.
