Tears, broken wine glasses and Kim Richards almost getting choked out .... yep, this was one "Real Housewives of Beverly Hills" battle that we won't soon forget.
What was supposed to be a peaceful trip to Amsterdam quickly turned into one of the most shocking fights in the series' history. This one's right up there with Teresa Giudice's famous table flip.
Kim has been battling speculation she's fallen off the wagon all season long, after one extremely loopy appearance at a casino night a few episodes back. She insists she took some bad medication, but Lisa Rinna and a few of the other cast mates aren't buying it.
It came to a head on Tuesday night, as Rinna revealed the reason she's so concerned about Kim is because she lost a sister to an overdose. Richards insisted she's been sober for three years -- and then proceeded to GO OFF.
"I'm concerned about you, at your situation at home. You wanna bring out my stuff, let's talk about your home life," she said to Rinna ... with some serious anger building.
Eileen Davidson started to interrupt her and defend the "Melrose Place" alum, but Kim wasn't having it. "Shut your f**king mouth, I've had enough of you, you beast! I don't like you," she shouted at Eileen.
Kyle just looked on in shock.
Richards then really started digging into Rinna, threatening to expose some secret Lisa allegedly wouldn't "want out" about her husband, Harry Hamlin.
This sent Rinna into a rage, as she reached across the table, almost slapping and/or choking Kim ... before standing up, throwing her drink on her and smashing her wine glass on the table.
Kyle was seen running away.
Even though Lisa said she never wanted to talk to Kim again, the two managed to have a civil conversation later in the day. It sounds like Richards just didn't want them to keep talking about her sobriety on the show, in front of all the other women -- and she would have preferred to talk privately.
They both apologized to each other and moved on ... but it remains to be seen how the other women will feel about it going forward.
What do you think of the absolutely explosive fight? Sound off below!
