Last week things got heated between Brandi Glanville and Kim Richards on The Real Housewives of Beverly Hills -- and the mudslinging continued in earnest Monday night.

When Kim and her sister Kyle Richards began giving Brandi a hard time about her parenting skills -- Brandi stood by while her son peed on Adrienne Maloof's lawn at an earlier get-together -- Brandi snapped.

"She's cracked out of her [expletive] mind," Brandi said, referring to Kim, who had been disappearing to the bathroom repeatedly and acting disoriented all night.

"You are trashy and classless," Kyle spat, defending her sister.

"At least I don't do crystal meth in the bathroom all night," Brandi shot back.

The other Housewives were absolutely aghast at Glanville's accusation.

"The crystal meth [comment] was way too far, way too far," said Camille Grammer in a post-incident interview.

Taylor Armstrong said, "I know Kim was not doing crystal meth. But I do worry about her, because I do think she is disoriented."

Taylor even broke up a physical fight between Kim and Brandi, screaming, "There will be no touching each other! Nobody is going to lay a finger on anybody in this house!"

Taylor Armstrong alleges she suffered abuse at the hands of her deceased husband. Russell Armstrong killed himself in August.

Brandi Glanville is the ex-wife of Eddie Cibrian, who left her after his affair with LeAnn Rimes was exposed. He is now married to the country star.
