Brandi Glanville has seen her share of catfights -- via Twitter, at least, with LeAnn Rimes -- but nothing really prepared her for the "Game Night" massacre on last week's episode of Real Housewives of Beverly Hills.

At Dana Wilkey's not-so-fun bash, Glanville (the ex-wife of Eddie Cibrian, who left her for Rimes) got into it with sisters Kyle and Kim Richards; Kim called Glanville a "slut pig" after Glanville accused of her doing "crystal meth" in the bathroom.

Still, Kim seemed a little off. What was going on? Kim has "some issues," Glanville told Us Weekly during a recent visit to Us Weekly with castmate Dana Wilkey.

The outspoken new star of the show opens up a little more about her foe's state of mind -- plus, she opens up about how things are going with ex Cibrian and Rimes these days. ("Things are still tense!")

Also in the chat? Wilkey models her $25,000 (!) sunglasses.
