West Wilson’s fellow “Summer House” cast members called him out for “lying” in the first look at the Season 10 reunion.

Kyle Cooke began the clip, which aired at the NBC Upfronts on Monday and circulated on social media, by telling Ciara Miller, Carl Radke, Ben Waddell and Mia Calabrese to “focus on West’s ease of lying” during their sitdown.

“We know that he had a full-blown exclusive relationship since February of 2025,” the Loverboy creator, 43, continued, referencing Wilson’s ex Meija Moreno. “We have receipts.”

Miller, who doubled down on Cooke’s claim that Wilson, 31, “had a girlfriend this entire time,” clapped her hands together in excitement.

“Can’t wait [for the receipts],” Calabrese said.

Miller — who dated Wilson in 2023 and reportedly hooked up with him earlier this year — wore a revenge dress to the April 23 reunion taping.

Wilson and Amanda Batula, 34, went public with their “connection” in March after weeks of rumors.

At the time, Page Six reported the Bravolebrities are in a “full-blown” romance — and that Wilson had been exclusively dating Moreno when the scandal came to light.

We heard Wilson and the Snarl Studios creator, 28, had been “exclusive” since the fall/winter of 2025.

He allegedly assured Moreno he was not sleeping with anyone else.

Last month, the sports journalist insisted on his “Show Me Something” podcast that “there was no overlap” and “everyone was single.”

He claimed, “I know there are a thousand different theories right now, but that is one thing that for sure did not happen. We realized things were maybe a little bit serious in February, and that’s when this all started. There’s not a whole lot more to it than that.”

Wilson and Batula are still going strong, making headlines in recent weeks for their New York City date nights — and even put on a united front, leaving the reunion.

In a viral leaked audio clip from the reunion, Miller eviscerated Batula for being a “f–king snake” for dating Wilson, with the graphic designer defending their relationship, saying people “can’t help who you like and are attracted to.”

She went on to acknowledge the “layers and complications” to their romance, from “the fact that [he] was seeing other people” to “the fact that [she] was still married” to Cooke.

Batula and Cooke, 43, announced their separation in January after four years of marriage.

Cooke shaded Wilson post-reunion for having “zero intention or integrity” and being “all PR.”

He recalled via Threads, “The reunion was a brutal beatdown, and I can’t recall a moment when he had Amanda’s back.”

The “Summer House” Season 10 reunion airs on Bravo May 26 at 8 p.m. ET.
