Cooper Koch reveals that he didn’t use a prosthetic while filming a nude shower scene in Monsters: The Lyle and Erik Menendez Story.

Koch, who plays Erik Menendez in the Netflix crime drama series, confirmed that he went au naturel during his Monday, October 14 appearance on Bravo’s Watch What Happens Live.

“Well, that was gonna be my next question!” Cohen, 56, replied. “Congratulations to you, Cooper.”

Koch mouthed “thank you.”

“You’re very blessed, aren’t you?” Cohen asked.

“Well hung,” Koch quipped.

Both Koch and onscreen sibling Nicholas Alexander Chavez (Lyle Menendez) have garnered tons of buzz since Monsters premiered last month. The controversial scripted show, created by Ryan Murphy, centers the Menendez brothers’ high-profile trial for killing their parents in 1989 and explores their claims that they were sexually, physically and emotionally abused by José and Kitty Menendez.

“I believe both of them,” Koch told Vanity Fair earlier this month. “I believe everything that they said on the stand to be true.”

However, Chavez, 25, hesitated to vocalize his opinion on the brothers, saying, “I came to a really unique conclusion, but I’ve also come to the conclusion that I don’t really want to share what that is with anyone, and that I really want to keep that part of my artistry and my interpretation to myself.” 

Koch recalled the moment in September when he visited Erik and Lyle in prison with Kim Kardashian, who has become a vocal activist for criminal justice reform. While Koch had previously spoken to Lyle, he had yet to talk with Erik, a critic of both Monsters and Murphy.

“It makes sense that he would feel that way,” Koch told Vanity Fair. “This is the worst part of his life being televised for millions of people to see, and not to mention in this dramatized, fictionalized, Hollywood TV way. I get how he feels, and I stand by him.” 

He recalled to the outlet that he hugged Lyle and Erik during his visit. 

“I got to give them a hug and look them in the eyes and just tell them that I believe them and I stand with them, and I’ll do everything I can to advocate for them.”

Koch added, “I know where I stand. I know what my point of view is, and that point of view aligns with all of the people on TikTok who support them. I know that I did everything that I could to support them and advocate for them in my performance, and portray them as authentically as possible. And if people are criticizing it, I know that I did everything I could.”
