Tea is being spilled — and mocked a little, too. If you’re a Real Housewives of Beverly Hills fan, you know that’s just the way Lisa Rinna pops off. The 56-year-old firecracker took to her Instagram feed to respond to reports she will soon be revealed as a ~fake friend~ to costar Denise Richards.

“I’m about to be exposed,” the bombshell actress captioned a throwback photo of herself posing nude, even including the monkey covering his mouth emoji. She conveniently censored herself with black bars.

According to Us Weekly, the former soap star and her 48-year-old castmate had a falling out while filming season 10 of the hit Bravo TV series.

“Behind the scenes, Lisa Rinna is continuing to be the instigator and continuously stir the pot for maximum drama. Rinna does this to make herself relevant and maintaining job security,” an insider revealed to the outlet. “Denise has had enough of Rinna’s constant meddling and passive aggressive behavior, especially with social media. Denise and Rinna are headed toward a showdown on camera, which is what Rinna has wanted.”

The source even went as far as to say that Lisa might get what has been coming to her via the climax of this particular feud. “Rinna is going to be exposed and held accountable; if Denise is the one to do it, bring it on.”

On December 17, Lisa called out Denise on Instagram over skipping an event at costar Dorit Kemsley‘s house. “Denise are you OK? You never showed up to Dorit’s Sat night, we were all so worried about you. What happened?!” she commented on Denise’s post about a recent health scare. “You said you were coming, you were meeting Garcelle [Beauvais], we never heard from you. What happened?”

While Denise has yet to publicly respond to the inquiry, longtime RHOBH star Camille Grammer decided to come to her aid on Twitter. “Denise did not quit #RHOBH and Rinna, you throw your friend under a bus,” the 51-year-old tweeted on December 18. “How about calling her to see how she’s doing and stop tweeting about it.”

Rinna wouldn’t let that comment go unresponded to, so she replied, “I did reach out to her privately. Thank you for your concern, Camille.” Welp, it looks like we’ll have to keep our eyes peeled on all this drama!
