We're not sure who Justin Bieber's new friend is, but they two got awfully close on the beach near Biebs' Laguna Beach condo, wrestling shirtless in the sand. But hey, we're not complaining!

Justin and the dude took a walk along the shore and as the afternoon temperature rose, they decided to take off their shirts -- and let's just say Justin didn't really have any competition. Bieber's tatts were in full display and his shorts were riding dangerously low. Seems the two were having a heart-to-heart and then had to blow off some steam with a little boy-on-boy beach wrestling. Hey, whatever releases the tension!
