High School Musical hottie Ashley Tisdale gets casual in a plaid shirt and totes around her Prada brown leather handbag while out and about in Los Angeles on Thursday.

Tizz, 23, is getting set for the High School Musical 3: Senior Year opening on Oct. 24 and recently said, “The set decoration is insane and beautiful. To think, in the first movie, we only had a ladder! Everything’s bigger, from details like the wardrobe, because of how big the screen is, and the musical numbers are so much bigger!”
