"High School Musical" stars Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Lucas Grabeel and Monique Coleman recently reunited in a gym made to look like the Wildcats' home court to film segments that will air during the anniversary telecast on Jan. 20 at 8 p.m. ET.
Disney apparently couldn't throw enough money at Zac Efron to appear with his co-stars in person, so Troy Bolton will pre-tape a video message to fans. Seriously, Zac Efron hates "High School Musical" only slightly less than Robert Pattinson hates "Twilight." Must be the glitter factor.
