Angle, posing and clothing can make a person look better/worse. I was in that industry a million years ago so I know that only THE ONE GOOD PIC is used for print and yea, many. many pics are *corrected* to some extent for a host of reasons. The one cover photo DOES seem to be fairly photoshopped because of the size of her behind and the girth of her arm. True in the pic where her arms seems very sloppy fat, because her bicep is flexed it would explain why her upper arm appears to be bigger. But it would be bigger in a tighter way, NOT in a sloppy fat way. And her lower body is in similar (though admittedly not the same) position. White will make ANYBODY look bigger, not smaller. The fact that her behind is cut by shirt and black pants that are obviously ill-fitting make her behind look ENORMOUS. Also she has a bad upper to lower body ration - small boobs HYUGE rear make her rear look even bigger.
I feel badly for celebs to a great extent. It must take a lot out of a person to be constantly scrutinized when they aren't really out to hurt anybody. I mean, this girl is a singer who isn't really ruffling any feathers.. is she? And even if she were, it's not like she's got dogfights on her property (ala Vick) or sleeping with her adopted daughter (Woody Allen) so why are people being so harsh?
She's got a HYUGE butt. So?
