Butt Implants! Yay! We rarely get to talk about butt implants here at Celebrity Plastic Surgery, so we get pretty excited when the oppurtunity arises. It seems as if Karrisa and Kristina Shannon, Playboy Playmates and former stars of The Girls Next Door have given us such an oppurtunity. The twins, who also appear to have gotten breast augmentations in recent years, are currently starring on Celebrity Big Brother, and a recent challenge had them flashes their butts, and those butts did not look natural. They have an awkward shape to them for one thing, as they’re too round. Secondly, they’re both ultra thin and not super-curvy, so their butts looked stapled on (think of a bad boob job on a really thin girl). Finally, their butts hang in an awkward manner, making it seem like their bodies aren’t used to the added posterior weight. So yes folks, those butts are probably the result of plastic surgery, and they’re definitely not the best butt-jobs we’ve ever seen.
