The Real Housewives feud between Kyle Richards and Brandi Glanville rages on!

One week after Glanville worried Richards and her fellow Beverly Hills Housewives thought of her as "super slut," Richards is digging into Eddie Cibrian's model ex even more.

During a game night on Monday's episode, Glanville, in a cast and on crutches, laments that she can't get along with any of the wives, save for pal Adrienne Maloof. "I felt like I had no friends in that room. Had Adrienne been there, it would have taken the edge off," she reasons.

To make the night more interesting, Kim Richards decides to hide Glanville's crutches as a prank. "She hates us," Kim says to sister Kyle, who offers a sinister laugh.

Then it's Kyle's turn to attack her foe. "[Let's take an] IQ test next," Kyle says, gesturing to Glanville. "You first."

Glanville's even-keeled retort? "Bring it, bitch!"

As tension builds, cast member Camille Grammer is anticipating the worst.

"Brandi doesn't know what she's getting herself into," says Grammer. "I wouldn't go there, girl."

Watch more of the Richards sisters' pranks on Glanville in the clip above before the Real Housewives of Beverly Hills airs Monday at 9 p.m. (EST) on Bravo.
