Zac Efron: Rock And Or Roll?!?!

Hiding behind a pair of shades, a solo Zac Efron sports a cool “Rock and or Roll” t-shirt with a brick wall design while out and about in Los Angeles on Wednesday morning.

The 20-year-old High School Musical star hid his face from photographers soon after they started snapping away.

Zac‘s on-and-off-screen girlfriend Vanessa Hudgens has been making the New York City rounds promoting her sophomore album, Identified.
