Kyle Richards is furious with her sister Kim Richards and she's pissed off that she's siding with her 'friend' and not her own blood.

Kim Richards Choosing Brandi Glanville Over Her Own Sister?

The drama between Real Housewives of Beverly Hills stars Kim and Kyle has been the forefront of the last several episodes, and the war is not even close to over.

In a Bravo sneak peek for Tuesday night's new episode, Kyle confronts Kim for not having her back during her fight with Brandi Glanville. Glanville and Kyle have been feuding since Eileen Davidson's poker party and the explosive drama between the two ladies is only heating up.

Kyle Richards & Brandi Glanville Almost Come To Blows

In the video, which can be seen below, the two sisters meet up for lunch to discuss the issue that took place, and Kyle becomes furious when Kim acts like she didn't hear the nasty remark Glanville made about Kyle's husband Mauricio.

During Kyle's Gay Mixer, Kyle and Glanville almost came to blows, and before walking out of the party Glanville made a nasty comment about Kyle's husband not wanting to be with her.

Oddly enough, neither did Glanville's husband, hence his decision to leave her for another woman. The point is, Kyle is furious that Kim didn't stick up for her at all and she's calling her out for taking Glanville's side.

Kyle is clearly upset, and she's tired of her sister not having her back. Be sure to tune in to next week's episode to watch the drama unfold. 

Real Housewives of Beverly Hills airs every Tuesday night at 9 p.m. on Bravo. Viewers can watch a sneak peek of the new episode in the video below.
