They don't call it Small Lake City for nothing.

The Real Housewives of Salt Lake City's Heather Gay is shedding light on a surprising connection between one of her former costars and The Secret Lives of Mormon Wives' Demi Engemann.

"I know Demi and Bret [Engemann] because that's Angie Harrington's ex-husband," the Bravo star exclusively told E! News, "and we're good friends."

That's right, Demi's husband Bret used to be married to the RHOSLC alum and the exes even share two children.

"It’s Small Lake City, totally," Heather noted, adding that she's still close with Angie, who left after season three in 2022. "She lives a little bit farther away from me, but we still stay in touch."

As for the new Hulu reality series, which follows a Mormon community of #MomTok influencers who were embroiled in a swinging sex scandal several years ago, Heather is a huge fan.

"I didn't know the others, but I totally watched and I loved it," she gushed. "I felt like it was Housewife adjacent, a lot of the things that they talked about on their show we've addressed on Housewives."

And although the group of TikTokers nearly broke the internet after member Taylor Frankie Paul revealed some couples participated in "soft swinging" together, the extra-marital escapades were something Heather was already privy to.

"#MomTok really brought it to a forefront and I didn't realize it was younger people," the 50-year-old admitted. "I knew of soft swinging and I knew there were some soft swinging with locales in Utah. Everyone heard legend of it, but I always thought it was older people. #MomTok was the first time I heard about soft swinging for the under 30 set."

And while season five of RHOSLC—which premieres tonight, Sept. 18—won't feature any sex scandals, the cast is rocked by one costar secretly recording the other Housewives.

"Have you met the Salt Lake City Housewives? We're a pretty tech savvy bunch of ladies," Heather joked, referencing last season's Reality Von (Tea)se cyber bullying scandal involving series alum Monica Garcia. "We are hypersensitive to surveillance videos and being secretly recorded and being exposed. So, we're on high alert and it picks up throughout the season."

"It was crazy," she noted, "expect the unexpected with Salt Lake City. We're snowflakes for a reason because we bring a storm. A lot of bad weather."

See the drama play out when The Real Housewives of Salt Lake City premieres Wednesday, Sept. 18, at 9 p.m. on Bravo.
