Zac Efron proudly displays his 'Baywatch' bod

With production on the new Baywatch movie beginning this week, paparazzi have been on "bae watch." By that, we mean plenty of shirtless photos of stars Dwayne "The Rock" Johnson and Zac Efron have been snapped by photographers.

But Efron isn't upset about the attention. In fact, he shared one photo of himself that may have been taken by someone hiding in the bushes.

Efron also shared an pic of himself battling Johnson-- and losing (his shirt).

Johnson explained that the photo captured their "tire shrugging contest." So we're going to give a lot of credit to Efron for even attempting to battle Johnson in a physical challenge.

When The Rock calls you a "meathead," you know you are Baywatch-ready. Way to go, Efron!
