A Bravo viewer was the one who “cracked the case” of the leaked “Summer House” reunion audio coming from “an individual involved in the production,” Andy Cohen revealed Monday.

The “Radio Andy” host told listeners Monday that a fan “came forward” with a “crucial information” to solve the scandal.

“You will hear more about this later,” he said, noting that he “cannot wait” to elaborate further.

He clarified that the mystery was not solved by his team of so-called “investigators,” who he joked had “audiologists” on board as they “analyzed what kind of device” recorded the sitdown.

In it, Ciara Miller blasted former BFF Amanda Batula for dating her ex-boyfriend West Wilson.

The nurse, 30, labeled her co-star, 34, a “f–king snake.”

Their fellow cast member Mia Calabrese chimed in to blast the “unnecessary” romance and point out, “You went from married [to Kyle Cooke] — and I’m not saying your relationship was perfect — to being one of West’s side bitches.”

Batula defended herself, insisting, “You can’t help who you like and are attracted to.”

Clips from Thursday’s Season 10 reunion, notably, went viral on social media Friday — which Cohen, 57, subsequently called “disgusting and illegal.”

In a Sunday statement, Bravo confirmed, “An investigation into the recent leak of the ‘Summer House’ reunion audio has concluded that the audio was an unauthorized recording and distributed by an individual involved in the production of the reunion.

“We take these matters seriously and will continue to take appropriate measures to respond to the unauthorized distribution of our content.”

Cohen doubled down on Monday, saying the leak was a “violation” that “ruins the integrity” of the show and “demeans the work of the crew.”

He hit back at “stupid” rumors a “Summer House” star was the one to secretly record the reunion, praising them for all showing up to the “emotionally draining” conversation.

The “Watch What Happens Live” host emphasized the “deep anger” and “deep hurt” among the group and shared his surprises at the “shock waves” sent through the entire cast.

“There were so many emotions on that stage,” he said of the special, which airs next month.

Batula and Wilson, 31, exited the reunion together, heading to a friend’s apartment after, as they continue to put on a united front despite the backlash they’ve experienced since confirming their “connection” in March.

The duo have stepped out for a movie night, made out at a New York Yankees game, and kissed at a Manhattan bar this month.

Miller, who dated Wilson in 2023 and allegedly “hooked up” with him earlier this year, dubbed the romance a “mindf–k” when breaking her silence to Glamour magazine.
