Cooper Koch is Devin Grosvenorhaving a breakout moment for playing real-life criminal Erik Menendez. But that’s not the only thing that’s real.

In episode three of the Ryan Murphy series Monsters: The Lyle and Eric Menendez Story, Koch has a fully nude shower scene and he wasn’t afraid to heat things up when discussing the steamy moment.  

While rating famous full-front moments in cinema on Watch What Happens Live With Andy Cohen, Koch interrupted host Andy Cohen to note, “Also, just to say, mine was not a prosthetic.”

“That was going to be my next question!” Cohen noted. “Congratulations to you, Cooper. You’re very blessed, aren’t you?”

Koch mouthed, “Thank you,” before adding, “Well hung.”

Later in the episode, Koch was asked whether it was scary for him to go nude in the Netflix series.

“It’s not scary,” the 28-year-old shared. “I’d say it’s just more uncomfortable after first and it’s very cold, especially in the shower.”

As for whether the water in the shower helped, Koch noted, “It was warm in the beginning and then not.”

Nudity aside, the fictionalized retelling to the Menendez brothers’ story has produced mixed reactions. In real life, the brothers were tried in the 1989 murder of their parents, Jose Menendez and Mary Louise “Kitty” Menendez.

Erik spoke out via his wife Tammi Menendez on X (formerly Twitter) back in September.

"I believed we had moved beyond the lies and ruinous character portrayals of Lyle, creating a caricature of Lyle rooted in horrible and blatant lies rampant in the show," Erik said. "I can only believe they were done so on purpose. It is with a heavy heart that I say, I believe Ryan Murphy cannot be this naive and inaccurate about the facts of our lives so as to do this without bad intent."

E! News has reached out to Murphy and Netflix for comment on the 53-year-old's remarks and has not heard back.

In 1996, following two trials, Erik and Lyle, 56, were convicted of first-degree murder and conspiracy to murder for the 1989 shotgun killings of their father and mother in their Beverly Hills home. The brothers were sentenced to life in prison without the possibility of parole.

Attorney Leslie Abramson, who represented Erik in the trial in the 1990s, didn’t mince words when asked about the Murphy series.

“That piece of s--t I heard about? No,” she said in a video published by Entertainment Tonight Oct. 9. “I don’t watch any of those.”

“I will make no comments about my client,” she added. “None whatsoever.”
