Everybody knows Mariah Carey is the true Queen of Christmas—she established herself as such back in 1994 when she released "All I Want For Christmas Is You," and has kept her festive reign over the holidays for nearly a quarter of a century. Still, she isn't the only celebrity to take things to the next level every December. The Kardashians, the Hiltons, and the Smiths have all given each other a run for their money in terms of who can be the most extra on Christmas, with all manner of over-the-top Christmas cards, poses on Santa's lap (or with the Grinch), and ugly holiday sweaters. Of course, there is no better place to be extra about the holidays than on Instagram. Here the most extra of the extra celebrities—when it comes to the holidays, anyway.
