Yeah that would be strange if Lily traveled to Milan to do the Dolce&Gabbana show, presumably as a special request and then got cancelled; although Lily is one of the few models who makes enough $$$$ so that if she got cut, or if indeed she knew that there was no guarantee that she'd get cast, then she can just turned it into an opportunity to shop, hang out with friends or go to castings for printwork; heck with it being Lily we'll probably see her in an Italian ad campaign or catalog in a few weeks (ka-ching!).
So does Lily actually have a bad walk or is it that she does silly stuff on the VSFS runway?
