K.J. Apa & Charles Melton on Riverdale (2019)

This week's new episode of The CW drama Riverdale got K.J. Apa and Charles Melton shirtless. Despite being seemingly left at death's door in last week's episode, Archie (played by K.J.) showed back up in his hometown healed from his chest wound this week. It was proven to viewers as he got multiple scenes without his top. The first was a locker room scene where Archie had a confrontation with Reggie (played by Charles Melton). Both boys were shirtless for the occasion. Archie removed his shirt again later for a very brief love scene and then again at the end of the episode, as he practiced throwing punches in his bedroom.
