Ciara Miller isn’t buying Amanda Batula and West Wilson’s relationship.

In the first trailer for the explosive “Summer House” Season 10 reunion, which dropped Tuesday, the model claims her ex only started dating her former bestie “to spite” her.

“Over the past six years, I have been your f—king champion,” Miller sternly said to Batula, as they both sat in the hot seats closest to host Andy Cohen. “I couldn’t fathom that I’d be sitting here pissed that you’re f—king my ex.”

Miller continued, “He wants to embarrass me. He wants to get his last little word. And I hope it works, because he’s with you to spite me.”

Despite Miller’s harsh claim, the couple put on a united front elsewhere in the trailer when they kissed each other in the dressing room as they prepared to face the rest of their co-stars.

And once the cast was seated for the highly anticipated reunion, it appears emotions ran high.

“What’s going through your mind?” Cohen asked castmate Jesse Solomon at one point, who could be seen holding back tears.

“I feel like I’m losing a brother,” he replied, referring to Wilson. “I hope you can somehow improve and prove us wrong. But it doesn’t look good.”

In another intense moment from the trailer, Kyle Cooke — who is currently separated from Batula — sadly said he thought Wilson was his friend, and noted that he was “going back and forth between feeling concerned and feeling betrayed.”

The trailer concluded with Batula storming off and crying — while Wilson remained seated on the couch.

Several of his co-stars urged him to follow after her, with Lindsay Hubbard screaming, “Get up and go after her, West. Be a f—king man.”

Batula, 34, and Wilson, 31, shook the Bravo universe back in March when they confirmed their secret relationship via a joint Instagram statement.

Cooke and Batula announced their separation after four years of marriage in January. Meanwhile, Miller and Wilson, who first dated back in 2023, were rekindling their romance during Season 10, which filmed last summer.

Since then, the rest of their “Summer House” crew distanced themselves from the duo, but have continued to take swipes at them online.

Part one of the “Summer House” Season 10 reunion airs May 26 at 8 p.m. ET on Bravo.
