Zac Efron: Sweaty Gym Guy!

Zac Efron leaves the gym drenched in sweat after a workout on Wednesday (February 16) in Inglewood, Calif.

The 23-year-old actor grabbed a cup of coffee from Starbucks to give himself a boost before he arrived at the gym earlier in the day.

The night before, Zac attended the opening night performance of Rock of Ages at the Pantages Theatre. The musical features 80s rock music and former American Idol contestant Constantine Maroulis!
