Judging from many of the "real-life" pics of her posted on this forum, the Playboy Photoshop Guy should be losing a few pounds before her shoot, too. He's going to need all the energy and stamina he can muster.
There's been rumors of her doing a Playboy spread (te he) for eons, so I'm skeptical, but if it turns out to be true that's wondeful. Body-wise, I think she should've done if a few years ago, but she was still floating on the whole innocent pop-singer blimp at that time. That time is certainly no more. Problem with Playboy is that, if she does actually appear in it, they'll airbrush out any of those little details that actually make someone look human.
