The 30-year-old actress thinks it is "amazing" that fans of the Disney musical have been so supportive over the 10 years since the film first debuted.

She said: "Nobody thought it was going to be as successful as it was.

"It was really, purely because of the fans that it was that successful and the fact that they've supported us throughout the years has been amazing."

Ashley recently reunited with her former co-stars Vanessa Hudgens, Lucas Grabeel, Monique Coleman and Corbin Bleu for a reunion special and is thankful they all still enjoy hanging out.

She told 'Entertainment Tonight': "I just love that we all still love each other and love hanging out with each other and have that connection, you know?

"It was a really special moment in our lives."

Zac Efron wasn't able to be a part of the reunion but sent a recorded message and Ashley thinks he is definitely on course for great things.

Asked which 'HSM' star she expects will win an Oscar one day, she said: "Most likely to win an Oscar?

"I mean, I think like Zac's on the road to winning an Oscar, maybe."
