“Monsters: The Lyle and Erik Menendez Story” has sparked some deep conversations, but let’s be honest: Kuiper Koch‘s full-frontal shower scene was also a terribly hot topic.

The actor spilled the tea when he bared all for the Netflix show, cheekily admitting, “Mine wasn’t a prosthetic” during “Watch What Happens Live” — the statement came right after the host Andy Cohen pointed this out Mark Wahlberg wore a fake penis in “Boogie Nights” while counting down Hollywood’s “top five most iconic full-frontal moments.”

Cohen was all ears for the confession, excitedly joking, “That was going to be my next question!” Congratulations, Cooper. You are very blessed, aren’t you?’

Cooper clearly knew how to leave an impression both on and off screen… as he flashed a cheeky smile at the camera and replied, “Well… hung up.”

Of course, Cooper has received a lot of critical acclaim for his role as Erik Menendez in the Ryan Murphy show, with Nicholas Alexander Chavez step into the shoes of Lyle.
