Just because last week's episode of The Real Housewives of Beverly Hills played out without incident, that doesn't mean that the drama is over — especially not between quickly devolving archenemies Brandi Glanville and Adrienne Maloof (pictured), whose rivalry has been slowly heating up to the boiling point, with Brandi recently predicting that things are going to get ugly between her and Adrienne if they aren't resolved soon.

And on Monday night's Bravo episode of The Real Housewives of Beverly Hills, entitled "She's Gone Too Far" — the "she" referring to Brandi — the prediction proved prophetic when Brandi had some fighting words for Adrienne at a social gathering thrown by Lisa Vanderpump.

"This girl lies 24/7," Brandi said of her new nemesis. "She had too much time on her hands. She's not taking care of her own kids," she said.

Adrienne didn't hesitate to share her own opinions about Brandi. "Brandi crossed the line and hit below the belt," she said. "I can't believe Brandi would sink to this level … this is absolutely so classless."

And that's not all. Adrienne's hubby, Paul Nassif, got into the ring to duke it out, as well. "Someone says anything about my family, I'm not going to take it lightly," he revealed, also getting into Brandi's face and loudly calling her a "bitch" in front of everyone before he and Adrienne decided that they were both so upset they would have to leave.

The Real Housewives of Beverly Hills airs Monday nights on Bravo at 9 p.m.
