The claws are out on "The Real Housewives of Beverly Hills!" 

Brandi Glanville posted an open letter to Facebook on Sunday, blasting co-star Joyce Giraud for telling lies about her to stay relevant.

"Joyce’s ongoing comments, accusations and labels have endangered my family and cost me jobs, and opportunities," Brandi wrote. 

"As a single mother, supporting my two little boys and running a household by myself I hope Joyce feels really really good about what she is doing to my family as she sits atop her mansion with her giant diamond ring and zero worries," she added.

Glanville said she wishes Joyce "were more interesting so that trying to ruin my life wasn’t her only storyline."

Wow, those are some harsh words!

The blonde beauty hasn't exactly been on her best behavior this season.

On a recent episode, things got messy -- in more ways than one -- after Brandi had one too many drinks at dinner.
