Ashley Tisdale burst into tears while filming her final scenes for High School Musical 3: Senior Year - because she is devastated her part in the franchise is over.

The actress has been involved in all three of the hit teen movies so far, but won't be playing Sharpay Evans for a fourth time.

And she insists she wasn't the only one to shed a tear on the last day - her castmates Zac Efron, Vanessa Hudgens and Corbin Blue all got emotional too.

She says, "We went into the last day thinking, 'It'll all be fine 'cause we're all really good friends and we're so close."

"It wasn't even the last scene - we couldn't even get through it. We were crying and just so emotional over the whole thing."

"We're so attached to each other. We've had such fun doing these movies. It's definitely something that's tough to leave and say goodbye to."

Tisdale also confirms she is not the only one who will miss out on a further Disney follow-up.

She adds, "I heard they're going to do a High School Musical 4, but we have nothing to do with it. I think we're all doing other projects and moving on."
