Denise Richards Has 'Had Enough' Of 'Real Housewives Of Beverly Hills' Costar Lisa Rinna's Behavior

Denise Richards is over Lisa Rinna's "constant meddling and passive aggressive behavior." The Real Housewives of Beverly Hills stars were once BFFs, however, lately the Bold and the Beautiful actress is done with the Bravo star's antics.

A source recently dished to Us Weekly that Lisa, 56, and Denise, 48, had a big falling out on the upcoming season of their hit reality 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,” the insider told the publication.

On December 17, Lisa called Denise out for not attending costar Dorit Kemsley's house party. “Denise are you ok? You never showed up to Dorit’s Sat night we were all so worried about you. What happened?!” Lisa commented on Denise's Instagram post. “You said you were coming, you were meeting Garcelle Beauvais, We never heard from you. What happened ?” The post detailed the mother of three's recent emergency surgery to repair her hernias."Being a mom, wife, & having a career sometimes it’s easier to just be strong and power through, I thought the pain & my other symptoms would just go away. They did not and got a lot worse. I’m so grateful to @herniadoc & her fabulous team. I thought I had one femoral hernia, I actually had 2 femoral & 2 inguinal,” Denise explained in her caption.

Former RHOBH star Camille Grammer came to Denise's defense on December 18. “Denise did not quit #rhobh and Rinna you throw your friend under a bus,” the 51-year-old tweeted. “How about calling her to see how she’s Doing and stop tweeting about it.” The Melrose Place alum clapped back, “I did reach out to her privately. Thank you for your concern, Camille.”
