Ciara Miller and Amanda Batula go head-to-head in shocking audio from the “Summer House” Season 10 reunion.

In the alleged leak, shared via Instagram on Friday morning, the nurse questioned “why” her former BFF was dating West Wilson — Miller’s ex.

“You went from married [to Kyle Cooke] — and I’m not saying your relationship was perfect — to being one of West’s side bitches,” Miller, 30, said, dubbing the new romance “crazy” and “unnecessary.”

“There are a million other f–king guys in New York City and … you chose the one guy,” she continued before labeling Batula, 34, a “f–king snake.”

Miller added, “You’re a snake in the f–king grass … and you know you are. You move silent, but you’re f–king deadly.”

Elsewhere in the clip from the reunion, filmed Thursday, Miller called out Batula for denying rampant romance rumors when asked about them directly via text.

At the time, Batula allegedly replied, “Duh, we’re just friends.”

Miller blasted the couple for knowing “how f–king weird” their connection would be and “still [choosing] to do it.”

Defending herself, Batula explained, “It was all so new and I was figuring it out. There were so many layers and complications to this. The fact that he was seeing other people. The fact that I was still married.”

She also insisted “you can’t help who you like and are attracted to.”

Miller disagreed with this — and pointed out that Batula and Cooke, 43, are still legally married “by the state of New York” despite announcing their breakup in January.

Batula clapped back, “I’m sorry, when I’m separated from someone I have to stay celibate and single for the rest of my life until the judge signs paperwork?”

Reps for Bravo and Batula did not immediately respond to Page Six’s requests for comment.

Speculation began swirling about Batula and Wilson, 31, in March, with the duo confirming what Page Six hears is a “full-blown relationship” at the end of the month.

Batula defended the “rushed” statement during Thursday’s sitdown, saying, “There was a video out there and the last thing I wanted was for us to continue denying it and for this video taken of me in a very vulnerable and intimate situation to be used as blackmail or released publicly.”

After weeks of cryptic social media activity, Miller finally broke her silence on the betrayal in a Glamour interview — and confirmed she was most hurt by Batula’s actions.

“At the end of the day, a guy’s a guy,” she explained in the profile, published last week. “Whether or not West and I are working on a relationship, you just can’t put anything past a man.

“I just never would think that it would come from someone like Amanda, who has been what has felt like in my circle and in my corner for so long,” Miller noted.

She and Wilson dated in 2023, with Us Weekly recently reporting that the exes hooked up earlier this year.

Andy Cohen took to Instagram Stories after filming the reunion, dubbing it “one of the most intense” of the 200 he’s hosted over the years and confirming “every question was asked.”

The “Summer House” Season 10 reunion will air on Bravo May 26 at 8 p.m. ET., one week after the finale.
