Jennifer Love Hewitt's curvy-and-proud defense of her callipygian assets just earned her the cover of People magazine, but she's far from the only starlet dealing with intense physical scrutiny and self-image issues.

Let's start with Hayden Panettiere, who at the ripe old age of 18 has already suffered the indignity of having her enviably petite and athletic figure picked apart by the masses.

"Did you see TMZ the other day where I bent over and they took a picture of me, and there was a whole conversation on whether I had cottage cheese thighs or not?" the "Heroes" cutie asks People. "It makes me feel awful. I'm sorry, but no woman looks good under overhead lighting. It was not good lighting."

What's more, she says, "I'm a teenage girl and I have the same body issues. There are parts of my body that I don't mind, and there're parts of my body that I absolutely can't stand. And I don't need somebody pointing them out to me, because trust me, I know they're there."

Huffs Hayden, "You don't need to tell anyone else about it. It doesn't need to be strewn across a magazine. It's my business. And the fact that you don't have anything better to talk about than my thigh fat is absolutely absurd. It just goes to show you the pathetic people in this world."

Meanwhile, Hilary Duff, whose tiny frame is looking far more robust after previously dipping into lollipop territory, insists she's mellowed out when it comes to counting calories.

"There definitely was a time, about a year and a half ago, when I was pretty obsessed with my body and my weight, but I'm better not stressing about my body all the time," she admits to Cosmopolitan. "It's not attractive when girls get superskinny. Guys don't like it. Girls don't like you as much. You lose some happiness when that's all you think about."

Duff, 20, also delved into the poundage pressure during a sit-down with "Access Hollywood," explaining how it's a no-win situation.

"They said things before, you know like, 'Oh my gosh! She's gained weight!' And then I lose weight and then it's, 'Oh my god, she has lost too much weight!'" she says. "I think that when you just laugh about it and you don't let it affect you -- it's easier said than done, definitely, because it hurts your feelings and it gets to you, and we're just human."

Speaking of losing too much weight, Carrie Underwood's lately twiggy look has also been the subject of much speculation, but she tells Glamour that she achieved her bordering-on-Kate Bosworth-esque bod the old-fashioned way -- through diet, exercise and the detailing of every single morsel she tosses down her gullet.

"I'm slightly obsessive-compulsive about what I eat, more than I should be," reveals the blond warbler. "I write down everything I eat. I started doing it last year. And in the last year is when I've gotten more healthy and lost weight."

Says Carrie, "I feel like I do things the right way, the healthy way. I work out. I like cardio. That big exercise ball, we're friends."
