The 48-year-old appeared on the Wednesday, August 18, episode of Bravo's Chat Room and discussed the state of their friendship.
The Real Housewives of Beverly Hills alum told Gizelle Bryant and Porsha Williams that she is not speaking to the 56-year-old, but is unsure of the reason why. "This happens very often with us. But I'm talking to [her sister] Kyle [Richards]," Glanville said. "We take breaks because we will murder each other."
"I love her, I have nothing but love for her," the former reality star added.
"Kim and I [were] best friends and we will be again," she explained. "We just had, like, a hot tub fight and I don't know what happened — I know what happened — but we're not talking at the moment."
"The hot tub fight, literally, I was like, 'Where are the cameras?' She was drowning me," Glanville alleged. "But, we were having fun." However, she did not share what sparked the fight.
An insider told Entertainment Tonight that they had a moment that "turned into a bit of a vicious fight, but all in good fun" in the hot tub last year. The source said that Richards would not have been able to drown her pal as the water in the hot tub was only two feet high.
Glanville also addressed the state of their friendship earlier this year. "I am not fighting with @KimRichards11," she tweeted in April. "I will always love her I just haven’t heard from her since NYE & have zero idea whats going on but I am [not] fighting with anyone!"
This isn't the first time the duo's friendship has been on the rocks. In November, the Drinking and Tweeting author revealed that they were not speaking, due to rumors that they had a threesome with fellow RHOBH alum Carlton Gebbia.
"Kim Richards is still not talking to me," the My Kitchen My Rules alum said on an episode of her "Unfiltered" podcast at the time. "She said that she was upset about this threesome rumor. And I said, 'Are you joking?'"
However, Glanville tried to put the rumor to rest. "I have NEVER had a threesome with @KimRichards11," she tweeted the same month. "She is one of my best friends & that’s it. This is hurting our friendship please STOP!!"
