Have you noticed that Kristen Stewart has the same facial expression in every photo that's ever been taken of her? I mean, okay, technically I think I have seen her smiling (although I'm not gonna look it up, because ain't nobody got time for that), but mostly her posing-for-a-professional-photo face is ... stony? Sulky? Just sort of deadpan?
I don't blame her for not lighting up like a Christmas tree in front of the camera, since she's been pretty up front about her awkwardness and inability to convey emotions in a manner endearing to other humans. But when you really look at how she comes across in photos, it's downright freaky. She's not alone, either -- there are a handful of other celebrities who look exactly the same in every photo, despite hair, makeup, and styling.
