As they say goodbye to their onscreen alter egos, the cast of the High School Musical movies talks to PEOPLE about the past three years together – and dish on their real feelings for each other.
Like did you know Ashley Tisdale used to hate her HSM co-star Lucas Grabeel?
“We would hardly talk to each other,” Tisdale, 23, says. “When I was auditioning for [mean girl] Sharpay, I screen-tested with him and I was acting like Sharpay. I think he was like, ‘Who is this girl telling me what to do?'”
No worries, though. The two hit it off eventually and now treat each other like real-life siblings. In fact, the six stars say they have all grown into a real family onset.
“No one says it’s the last time,” Hudgens said. “Who knows what the future will bring?”
