Don’t be dissin’ on the Snopes, mo fo
I think the second worse thing she has done (the first being hiring whatever stylist dresses her) was waxing her eyebrows. Notice in the “fat” pictures she has either no eyebrows at all or pencilled in lines. It makes her look. . . bad.
She’s not fat. However, she does look out of shape and trashy. Of course, I’m not in shape, either, but I’m trying to change that.
The main problems-the clothes. Trashy, sloppy, cheap Goodwill style hooker. (NOT that there’s anything wrong with Goodwill, of course).
The make up-overly done, trashy.
The hair-long, stringy, too dark for her complexion, greasy, looks unwashed.
In short-Xtina looks like a ho and a slob.
She hasn’t put on all that much weight on her body, but her puffy face suggests, to me anyway, that maybe she’s taking Prednisone, which is a steroid that makes you gain weight and makes your face very puffy. The small amount of weight she gained would not make her face THAT puffy. But Prednisone will make your face puffier than your body. And, yes, it can happen that quickly. I know from experience. 
The only thing that made me wonder if it was her, is that her boobs seem to be a bit bigger than before. Also, that outfit is seriously hideous. I don’t think that any woman would look good in that outfit. As other posters have mentioned, she looks like she is in serious need of a shower.
I’d like to see pictures of her after she has washed her hair, and has put on a decent looking outfit. I suspect that she would look pretty good.
