Remember that infamous and ridiculous Christmas card the Kardashian/Jenner family orchestrated back in December? Of course you do.
Well, apparently things got a little crazy on the set of the shoot, and now there's a video that proves it.
Kim, Kourtney and Khloe Kardashian joined their mom, Kris, and sisters Kendall and Kylie Jenner in karaoke-style music video (of sorts). The song? "Lady Marmalade" from Moulin Rouge. The 2001 movie soundtrack version of the song was performed by Christina Aguilera, Lil' Kim, Mya and Pink.
