NBC Shares New Shirtless Clips Of Zac Efron & His New Bromance Buddy

Zac Efron got shirtless and wild last night with his new hunky adventurer friend, Bear Grylls, on NBC’s new nature survival show, Running Wild.

The 26-year-old Hollywood star embarked on a two-day excursion to put his survival skills to the test. Efron ate some worms, rappelled down a cliff, and of course found every opportunity to get shirtless with his new bromance buddy.

Watch the duo get dropped into the heart of the Catskill Mountains below:
