Apparently some dude followed Ashley Tisdale into a Trader Joe’s grocery store in the Valley, and snapped off these pics of her from behind, I mean you can’t hate on a creep for creeping, but you can question whether this is Ashley Tisdale’s ass or not, but more importantly, you can thank him for cropping out her face, a face that even with botched plastic surgery, is one better positioned face down in a pillow, or really anything you can pin it into, when you stare at her from behind…
