Asked how she’s been spending her summer, the ‘High School Musical’ star said, “I’ve been working. We still have ‘High School Musical 3′, which was more fun than work actually. We had an amazing time. And now I’m on a summer tour, hitting all the state fairs. So, that’s always a blast.” Watch the promo and interview below the fold.
