Another one bites the dust. Well, actually, it seems Carrie Underwood isn't biting on much at all these days. The Season 4 American Idol champ is looking slimmer than ever and I'm beginning to fear a bobblehead shape taking form before my very eyes. I remember reading past articles in which the blonde beauty said she loved pizza and other treats, but I'm not sure that holds true any longer. Don't celebs just say they love junk food, anyway? I can't say I'm shocked, because we've all seen this before: Hilary Duff ( definitely no longer Lizzie McGuire), Mary-Kate Olsen, Nicole Richie, Jessica Alba, Lindsay Lohan. But I wanted to believe that this country girl wouldn't succumb to the pressure and end up with red-carpet photos of her hair looking heavier than the rest of her. Yes, she's confirmed exercising more. Yes, she probably has a grueling schedule. You're right, I don't know what it's like to go on tour. But what will it take for this shrinking style to end?
