Nearly a month after Monsters: The Lyle and Erik Menendez Story premiered on Netflix, breakout star Cooper Koch finally revealed whether he actually revealed all in the series’ viral shower scene.

“Mine wasn’t a prosthetic,” Koch blurted out during an appearance on “Watch What Happens Live” on Monday, while host Andy Cohen counted down Hollywood’s “five most iconic full-frontal moments.”

As Koch grinned and pointed a gun at the camera, Cohen said, “That would be my next question!” Congratulations, Cooper. You are very blessed, aren’t you?”

“Well, hungry,” the 28-year-old actor replied with a smile.

Koch, who also donned his clothes in the 2022 indie horror film “Swallowed,” plays Erik Menendez in the streaming hit, which shot to No. 1 after debuting on Sept. 19.

Created by Ryan Murphy, the nine-episode series follows the real-life murders of multimillionaires José (Javier Bardem) and Kitty Menendez (Chloë Sevigny) in 1989 by their sons Lyle (Nicholas Alexander Chavez) and Erik.

The brothers, who were sentenced to life in prison without parole in 1996, have long claimed they shot their parents to end what they say was years of sexual abuse.

“I believe in both of them,” Koch, who recently visited Lyle and Erik behind bars with Kim Kardashian, told Vanity Fair earlier this month. “I believe that everything they said on the witness stand is true.”

However, Koch’s co-star Chavez remains tight-lipped about his thoughts on the controversial brothers.

“I came to a really unique conclusion, but I also came to the conclusion that I don’t want to share this with anyone and that I really want to keep this part of my art and my interpretation to myself. “, the 25-year-old soap star told the magazine.

In prison, Erik criticized “Monsters” as a “dishonest portrayal” of his and Lyle’s story – but also admitted he hadn’t seen it.

In response, Murphy, 58, defended his dramatized project as “the best thing to happen to the Menendez brothers in 30 years.”
