Did someone replace Jennifer Lawrence's butt with, say, Betty White's butt?

Everyone loves to look closely (sometimes too closely) at J.Law's amazing body, but she's trying to distance herself from one photo out there.

Jennifer was recently on The Late Show with David Letterman, and in addition to getting irritated at people who didn't realize she was joking about Meryl Streep at the Golden Globes, she called attention to a blue bikini photo in a tabloid, insisting it was doctored. "It is not my butt, and I will not take responsibility for it. It's a 90-year-old butt that's been Photoshopped onto my body and is posing as my butt."

Jen claims she is not photogenic and brought two examples of "unflattering" photos (shown right), one where she has no makeup and looks "bloated" and another at an awards show, also looking (in her words) "bloated." She’s willing to admit those pics are of her, just not the bikini shot.

It's kind of funny that she
brought those photos to mock in her self-deprecating way, and then went out of her way to make sure no one believes that was her butt in the bikini shot. Why does she care, and why call extra attention to it? Oh, Jen! You just wanted us to stare at your ass, didn't you?
