Ashley Tisdale Phones it in on Set (PHOTOS)

When you’re a busy legend-in-the-making such as Ashley Tisdale, sometimes you have to multi-task.

High School Musical alum was back on the Vancouver set of her new series Hellcats on Thursday, taking advantage of the breaks in filming to bundle up against the chilly Canadian climate and work her phone for all it was worth. Checking in with her beau, video director Scott Speer, perhaps?
