Zac Efron Wigs Out

Zac Efron sports a strange (and laughable) hairpiece on the set of his new movie Seventeen in Santa Monica, Calif. on Thursday

Say wha-aaaaaaaat?

Seventeen tells the story of a 36-year-old man, in need of a major life do-over, who wakes up in the body of studly high school senior Mike O’Donnell (Efron). Matthew Perry (Friends) plays the older version of O’Donnell. Michelle Trachtenberg (Buffy) and Melora Hardin (The Office) also star.

WHAT DO YOU THINK of Zac’s wavy hair — YAY or NAY?
