You're A Mean One, Janet J
Okay, to be fair to Janet Jackson, she only looks like she snarls at the Whos while perched atop Mount Crumpit in the picture above. In the rest of the pictures, she doesn't look like she's going to snatch away Christmas anytime soon. The photographer just caught her at her grinchiest moment.
Here's more pictures of Janet at London Fashion Week looking aaaaaaaaalmost as naturally gorgeous as La Toya (I don't mean that, La Toya). Janet was also lucky enough to pose with the sexy matchstick known as Tilda Swinton.
