Zac Efron & Adam DeVine Swing Shirtless into a Lake

Zac Efron shows off his ripped muscles while hanging out in a lake shirtless on Saturday (June 13) in Hawaii.

The 27-year-old actor was joined by his Mike and Dave Need Wedding Dates co-star Adam DeVine, who swung on a swing hanging over the body of water.

“Aloha �’�🏻😜,” Zac captioned the Twitter photo.

The guys are in the area shooting the movie. In fact, they were spotted filming an intense argument scene on the beach in Oahu the day before.
