There is a particular website actually, that is completely devoted to picking apart celebrity bodies. They have sections such as "baby bump watch" where they decide if someone is pregnant and not telling the world yet..."anorexics" where they chat about recent photos, and if it looks like the Olson twins have lost or gained 2 pounds this month...it even has "celebrity cellulite" where they blow up pics of celebs in shorts or a bathing suit, and magnify any ripple they see.
They did this with Hewitt, and I think it is disgusting.
Honestly, ANY magazine ad or cover is airbrushed, and photoshopped...so if a person is at the grocery store, of course they are not going to look like they did 3 weeks ago on the cover of Vogue. I just don't think it is fair for magazines to promote health, natural beauty, and so on...and then turn around and call someone fat for being human.
Some people will have cellulite, stretch marks, gray hairs, wrinkles, or whatever-no matter WHAT they weigh.
