Ashley Tisdale in red top: Hotties: Ashley Tisdale investigates the lunch menu at the food truck outside the set of Hellcats in Vancouver. The 25-year-old actress kept warm in a red sweater and joined costars AJ Michalka and Matt Barr (with brother Luke) in getting a bite to eat. Like many others, Ashley was grateful to see Demi Lovato back on twitter. “ddlovato is back on twitter! Yay!!!! Love that girl,” she posted.
