Zac Efron and Ashley Tisdale: ‘Rock of Ages’ Premiere Pals

Former “High School Musical” co-stars and bffs Zac Efron and Ashley Tisdale shared a laugh at the premiere of Rock of Ages on Friday evening.

Zac stepped out to support pal Adam Shankman, who he is rumored to be reuniting with for the comedy This Is Where I Leave You.

Ashley just booked a lead role in Scary Movie 5 and is gearing up for the premiere of her production company’s Bravo series “Miss Advised.”

Rock of Ages hits theaters on June 15.
