Kyle Cooke is presenting evidence.

The Summer House star claimed in a preview of the season 10 reunion that he has proof that costar West Wilson was involved with someone else while reigniting his romance with Ciara Miller last summer and while beginning a new relationship with his current partner, Amanda Batula.

In a teaser shown during the NBCUniversal Upfront event on May 11, Kyle urged Ciara and their costars Carl Radke, Mia Calabrese, and Ben Waddell to pay attention to West’s “ease of lying” when the entire cast—including Amanda, Lindsay Hubbard, Jesse Solomon, KJ Dillard, Dara Levitan Bailey Taylor, and Levi Sebree—sat down with host Andy Cohen.

“We know he had a full-blown, exclusive relationship since February of 2025,” Kyle stated in the reunion episode footage. “We actually have receipts.”

Ciara also chimed in, claiming that West, from whom she first parted ways in December 2023, “had a girlfriend this entire time.” Clapping her hands together, she added, “Can’t wait!”
