WATCH: The Kardashians Release Music Video, World Rejoices

Today the internet is the gift that just keeps giving.

It turns out that, as well as capturing their annual slice of festive ridiculousness, the Kardashian Kristmas Kard, in all its static glory (3D version also available), our favourite reality family spent the pre-Christmas period indulging in some terrible lipsyncing to Lady Marmalade (the Moulin Rouge version.

In case you're pressed for time, here are the highlights:

0.09 - Khloe being utterly unable to walk down steps in heels

0.28 - Kris Jenner.

1.00 - Kourtney's outfit. Seriously. It was ridiculous then, it's ridiculous now, AND she's massaging her own butt.

1.15 - Slow-mo posing of the highest order.

Xtina would be turning in her grave. However, as she's still alive, she's probably just revolving gently in her The Voice swivel chair.
