Perhaps in a nod to all the superheroes commandeering the box office this summer, Zac Efron strikes an uncaped crusader-like pose here with lucky damsel Ashley Tisdale on his back. The heartthrob joined his ‘High School Musical’ co-star in Malibu last week to celebrate the actress’ birthday. And although we’ve conducted an ongoing debate on this site about the wisdom of swimming in underwear, as long as Zac-man keeps cutting this fine figure, he can do whatever he wants. Zac Efron with just a bit of Calvin Klein underwear waistband unwrapped is a birthday gift that keeps on giving.








This is definitely from last year and they weren’t actually swiming, they just kinda went in the water for a few minutes. These pics are still hot though.
Um this was ashleys birthday last year
