‘Summer House’ star West Wilson was in an ‘exclusive’ relationship with another woman when Amanda Batula romance was exposed

West Wilson was in an “exclusive” relationship with another woman when his secret romance with his “Summer House” co-star Amanda Batula was exposed, a source close to the situation claimed to Page Six.

According to our source, Wilson was actively dating Meija Moreno — who has been publicly referred to as “Montana girl” — as recently as last week.

According to our source, Moreno — who has since moved to the East Coast — has met and interacted with Wilson’s family and close friends, and the two became “exclusive” in the fall/winter of 2025.

We’re told Wilson, 31, assured her he was not sleeping with anyone else.

It’s unclear whether Batula was aware of the nature of Wilson’s relationship with Moreno, 28.

Wilson — who attended Montana State University — referenced his “situationship” with Moreno on “Summer House” Season 9, which filmed in 2024. (Season 10, which filmed last summer, is currently airing.)

He also gave her a shout-out during his appearance on “Watch What Happens Live with Andy Cohen” last week, saying his “friend Meija” had made his custom horse hair tie via her Snarl Studios company.

During the episode, Wilson was even asked about rumors he was hooking up with Batula, 34. He stumbled through an explanation, twice noting that she is “single.”

“I kinda gotta show her the streets, you know? … If it’s not clear, that’s a very important person to me, and I, like, care about her a lot,” he added, calling her “a friend” when pressed further.

Shortly after that appearance, our source claimed Wilson called Moreno to say he had been caught making out with Batula and that their secret romance was going to be made public.

Up until that point, we’re told Wilson had repeatedly assured Moreno that the rumors were just that — rumors.

However, on Tuesday — after Batula and Wilson issued a joint statement copping to their romantic “connection” — a source connected to the situation told Page Six that they are actually in a “full-blown relationship” and not just hooking up.

We were told their castmates — including Wilson’s ex Ciara Miller and Batula’s estranged husband, Kyle Cooke — are both “pissed” at and “disappointed” in the pair for lying to everyone.

Meanwhile, Us Weekly reported that Miller — who was best friends with Batula until this scandal emerged — and Wilson were “casually seeing each other” recently and trying to figure out “if things would work out again.”

As for Batula, she announced her separation from Cooke — who was close with Wilson — in January after four years of marriage.

Reps for Wilson, Batula, Moreno, Miller and Cooke did not immediately respond to Page Six’s requests for comment.
