Efron hits gym despite broken jaw

Actor Zac Efron's jaw may have broken his jaw following an accidental fall, but that hasn't stopped him from hitting the gym.

Just four days after slipping on a puddle and getting stitches, "That Awkward Moment star" was spotted working out in Venice, California Thursday evening, reports people.com.

"He looked great," said an onlooker, adding: "But it was all business. He was concentrating on hitting the weights hard."

Afron was wearing a long sleeved t-shirt and nylon pants.

"He seemed really pensive and was looking around to see who was looking at him," the onlooker said of the actor, who completed a stint in rehab earlier this year.

Efron refrained from moving his mouth, which was wired shut after the accident.
