There was some serious name-calling on Tuesday night's "Real Housewives of Beverly Hills" reunion -- as Brandi Glanville and Kyle Richards got downright nasty with each other ... and with their boss Andy Cohen.
Things between Kyle and Brandi have been volatile all season long, after Brandi became Kim Richards' new BFF and ally while displaying some troubling behavior. The two almost got physical at least once and have been talking behind each other's backs ever since.
Last night, Brandi was trying to tell Lisa that Kyle was spreading lies about her, saying Kyle told her Lisa Vanderpump was broke and hooking up with her personal trainer. This set Kyle off.
"You're a sick f**k," she screamed at Brandi. "Where does your hate come from? You are one of the most vile human beings I've ever met in my life."
"I hate you because you're horrible, you're a horrible person and a liar," Brandi retorted, before calling her the dreaded C-word. Yikes!
There's definitely more to come between these two next week ... and we can only imagine how ugly it'll be.
Brandi also got into it with boss Andy Cohen, who was hosting the reunion.
While trying to make an analogy about how Glanville sometimes takes things too far, he compared her to a dog ... something she wasn't too thrilled about.
"Forgive the comparison, but it's almost like you're playing with your dog and your dog bites you by mistake," Cohen said, the rest of women agreeing with him.
"F**k you," Brandi replied. "No, that's bulls**t, you don't say that. I've taken enough abuse since I've been here, I'm not going to take it from you too!"
Andy tried to explain that he meant it as a defense for her actions, but she wasn't buying it.
Elsewhere in the episode, we also got an update on things between Kyle and Kim Richards, who are probably at the lowest point in their sisterly relationship ever.
"I don't think the girls have helped, I think they have instigated and made things worse for us," Kim said of their troubles. "At this point right now, I am really OK with the way things are. This relationship for me. I'm happy in my life today is what I'm saying. I'm very happy today in my life. I miss you, I miss my sister, a lot, a whole lot."
The fireworks between these two are really going to go off next week though, as a teaser showed them screaming at each other and threatening to walk off the set.
Do you think any of these women will be able to patch up their differences? Sound off below!
