Okay, we have to declare that we're not really fans of the idea of Justin Bieber warbling all over what's almost been a Christmas classic since it was originally released 17 years ago. And it has to be said that we're not really fans of the finished product either.
BUT, what we are fans of is the video clip. Justin's peeps have gone all out to create something that encompasses the feeling of Christmas - especially all that bloody shopping (we're yet to start...).
Mariah looks fantastic in her Christmas outfit - and even manages to get a cameo for her dog Jackson P Mutley into the end of the clip.
We pretty much prefer the original (no-one else has done it better over the years), but this version is a bit of festive fun.
