An upcoming Real Housewives of Beverley Hills will see Brandi Glanville claim she had a steamy lesbian with co-star Denise Richards.
Brandi - often stirring controversy on the show - alleges that she and Denise shared a night of passion, before Denise orders her to keep silent about it.
She allegedly warned Brandi that [husband Aaron Phypers] "can never know."
In the clip, Brandi sits down to lunch with Kyle Richards, Dorit Kemsley, Teddy Mellencamp Arroyave, Lisa Rina and Erika Girardi, before Denise has arrived.
"I f**ked her," Brandi bluntly claims, "Woke up the next morning, she said, 'Aaron can never know about this. He'll kill me.'"

Later in the clip, acquired by PEOPLE, a tearful Denise slams the claims.
"What the f**k?!" she scolds, "That is not true!"
Mirror Online has approached Denise's rep for further comment, and her rep told PEOPLE that the affair didn't happen.

Dorit is firmly team Denise, saying she believes that the affair didn't happen.
Later, as some of the other housewives are gathered at a pool party, they lament that Denise is "a no show."
"I've been calling her," Garcelle Beauvais tells Kyle, "Nothing."
Concerned friend Dorit starts to get in a tizzy about her whereabouts: "I hope to God she's okay.

"My heart is racing. I'm really, really scared."
Near the end of the clip, Denise begs cameramen not to air anything about the alleged affair.
She claims that she'll walk if the network, Bravo, opts to go against her wishes.
"Bravo has a choice," she asserts, "If they ever want me to be on the show...they need to cut that."
Denise married Aaron in 2018, while Brandi divorced from ex husband Eddie Cibrian in 2010.
