It’s a hot one out there, and not just because of the scorching summer temperatures! K.J. Apa took to Instagram on Saturday, July 25, and posted the hottest pic to grace his Instagram in a while. In the snap, the Riverdale star, 23, could be seen across a rippling blue pool holding onto a long net after cleaning the pool just moments ago! He proudly showed off his ripped abs in the photo, too, turning the California temperatures way up!
