Wait a minute, let me get this straight. Nicole check herself into the rehab, but she doesn’t have the eating disorder, than she get out and all of a sudden her look has changed from anorexic skeleton to actually normal appearance.
There have been some rumours around Hollywood that she got gastric bypass operation the first time she got into the rehab, and that was the reason for dramatic weight loss she had. Doesn’t surprise me at all, as this is operation is just for obese people. She wasn’t that obese to have this done in the first place. Now the rumour goes that "rehab" was just a guise for her to get the operation reversed!
