BFFs Vanessa Hudgens and Ashley Tisdale (with puppy Maui) are seen leaving a rigorous four-hour dance rehearsal at a top secret location in Utah on Thursday. Of course, this was in preparation for their upcoming feature film, High School Musical 3: Senior Year, which also costars Lucas Grabeel. Also spotted on set, but not pictured below: Monique Coleman, Olesya Rulin, Chris Warren Jr and director/choreographer Kenny Ortega. Seems like the gang is all back together-but where's Zac Efron and Corbin Bleu?? Stay tuned for new pics from the set of HSM3, which has a tentative release date of Friday, Oct. 24.
