Zac on Set of his new movie!

Zac Efron takes a quick break to eat between takes on the set of his new film Seveteen in Southern Calif. on Wednesday.

The 20-year-old Seventeen star was seen shooting a backyard basketball scene as his character Mike O’Donnell, so this pic is his actually movie costume! The film tells the story of a 36-year-old man, in need of a major life do-over, who wakes up in the body of a studly high school senior.

Zac is a Brotha!

Zac Efron hides under a hoodie and sunglasses as he goes for his daily workout at a gym in Los Angeles on Wednesday.

Before heading to the gym, the High School Musical star dropped off girlfriend Vanessa Hudgens back at her house earlier that morning.

Zac, 20, wore a Nike zip-up hoodie and Arroyo Grande athletic shorts. (He attended Arroyo Grande High School.)
