Lisa Rinna is no stranger to feuds, but the top spot on the list of Rinna’s ex-friends probably goes to Kim Richards. Rinna and Richards have had a longstanding animosity, and when Rinna attempted to bury the hatchet by sending Richards’ grandchild a plush toy bunny, Richards returned the unopened gift claiming it didn’t have “good energy.”

Despite being friends for close to 20 years, Beauvais and Rinna had a falling out when the former joined Season 11 of “The Real Housewives of Beverly Hills.” As the only black woman on the show, Beauvais accused Rinna of racist microaggressions. Later, during the Bravo reunion, Rinnna denied the accusations, and the two seemed to make up.

When Denise Richards joined “RHOBH” in Season 7, drama quickly developed when Rinna spread rumors about Richards’ affair with former cast member Brandi Glanville. Richards denied the rumors, but when Rinna continued to bring up the Glanville drama, Richards left the show claiming that Rinna had thrown away a good friendship.

Before Lisa Rinna, Lisa Vanderpump was Bravo’s undisputed queen. This changed in Season 9 of “RHOBH” when Vanderpump spread some malicious press about co-star Dorit Kemsley. Rinna sided with Kemsley, and the tension escalated between the two when Rinna demanded payment for Vanderpump’s spin-off series, “Vanderpump Dogs.”

When Kathy Hilton joined “RHOHB” in Season 11, she quickly stole audiences’ hearts with her weird energy and quirky one-liners. However, Hilton didn’t return in Season 12, apparently because of Rinna. Rumor has it, Hilton will only return to the show if her sister Kim Richards is also welcomed back, but given Richards’ and Rinna’s feud, that seems doubtful.
