K.J. Apa on Riverdale (2017)

Episode 2 of the new CW drama series Riverdale got leading man K.J. Apa shirtless once again. His first scene of the episode found his character, Archie, attempting to sleep in bed while only wearing gray undies. With the investigation into his classmate Jason's death underway, Archie found himself struggling with his own partially-related secrets. After being rebuffed by his best friend Betty, he put on shorts and headed over to see his teacher (and summer fling) Miss Grundy. He didn't bother to wear a shirt, meaning viewers were treated to back-to-back shirtless scenes of the actor.
