Zac Efron showed off his lightened locks on the New Orleans set of The Paperboy yesterday. Both Zac and costar Nicole Kidman both went blond for their roles in the ensemble film, which also costars Matthew McConaughey and Tobey Maguire. Zac has been going straight from one project to the next this Summer, with only a short break between shooting Heartland in the Midwest and heading south for The Paperboy. Luckily for us, he's still able to keep up his fitness routine and hit the beach from time to time to show off those famous Zac Efron abs. Zac's ripped six-pack should serve him well in our annual shirtless bracket, which kicks off next week on PopSugar!
