High School Musical Heartthrob Zac Efron sneaks a look down Ashley Tisdale's top
Zac Efron has been snapped eyeing up co-star Ashley Tisdale despite standing next to his girlfriend Vanessa Hudgens, 18.
The hunky actor, 20, was posing with the girls to promote the DVD of High School Musical 2 on Monday when photographers snapped him taking a sneaky peak.
The actor couldn’t help himself peering down Ashley’s cleavage as she stood beside him dressed in a revealing purple frock.
But neither girls seemed to notice his straying glance and beamed happily at the cameras while Zac copped a cheeky eyeful.
