Ashley Tisdale and her ‘High School Musical’ chums

Ashley Tisdale (in white dress) poses on the red carpet with, from left, Vanessa Hudgens, Zac Efron, and Corbin Bleu. This was at the UK premiere of 'High School Musical 3: Senior Year,' held at the Empire Leicester Square in London, England on October 7, 2008. All were getting a *little* old to play high schoolers at that point: Ashley Tisdale was born in 1985, so she turned 23 the year this photo was taken. On the other hand, Olivia Newton-John was 29 when she played a high school girl in the 1978 film 'Grease,' so it's all a matter of perspective. Tisdale and Bleu look happy to be there; Hudgens and Efron look like their minds may be elsewhere.
