Zac Efron leaves his apartment for a check-up appointment at the Riverside Medical Building in Studio City, Calif on Sunday. (He was recently hospitalized due to appendicitis.)
On his way into the building, Zac dropped his car keys and gave photogs a great view of his blue boxer briefs.Damn,it looks gross. Someone should donate him a few bucks for Calvin Klein.
(What you're looking at?!My bum still looks way better than yours.)
