Never would Sharpay be seen in public sans makeup, but "High School Musical" actress Ashley Tisdale didn't seem to mind that fans were already lined up when she sauntered in to Mall of America at 8:30 a.m. Thursday for a sound check with nothing on her face but shades. Getting her glammed up (Janelle from Juut at Southdale helped) for her 11 a.m. concert, followed by a screening of her new movie "Aliens in the Attic" apparently took long enough that la Tisdale had NOTIME to hit even one store with me. (Too bad, I might have suggested a top that would have revealed a bit less of her black bra. You can try to go rock - but the 5-year-old fans bring you back to pop. The mismatched bracelets and biker boots were cool.) If she had walked the corridors rather than the secret hallways of MOA, she likes Urban Outfitters.
