Zac Efron is one of Hollywood’s busiest young actors… juggling multiple movie roles at the same time! The 23-year-old hottie, who recently buzzed his hair to play a marine in the upcoming war film The Lucky One, is grabbing some Z.E.N Food while doing voiceover work for the movie The Lorax, based on Dr. Seuss’ book. Z.E.N. Foods is a diet delivery service with calorie-controlled meals delivered to your front door. Why so healthy? We have a feeling Mr. Efron is gearing up for some shirtless scenes in The Lucky One. If that’s the case, we’re the lucky ones! Vanessa is missing out!
