Brandi Glanville claims she was manipulated and used by Kyle Richards.

Lisa Vanderpump & Brandi Glanville Get Into Heated Argument

In her April 1 blog for Bravo, the Real Housewives of Beverly Hills star claimed Richards used her as a messenger to spread rumors about Lisa Vanderpump and her husband, Ken Todd, whom Richards is currently friends with.

"Kyle DID backstab Lisa V. and Ken Todd last year," Glanville wrote on Tuesday. "She ABSOLUTELY told me Lisa V. had an affair and had filed a bankruptcy. I was simply used to deliver the message...on TV. My fault. I was manipulated and let myself be used. I have to take complete responsibility for that. I lived and learned."

Brandi Glanville Spent Her Weekend With Her Boyfriend & Two Sons

While Glanville and Richards aren't friends at the moment, they did have a brief relationship during filming on The Real Housewives of Beverly Hills season 4, which was reportedly when Richards enlisted Glanville to do her dirty work.

"What's odd is that Lisa V. and Kyle obviously don't like each other and have nothing in common," Glanville continued. "Lisa V. is quick and smart. Kyle is slow and not smart. They use each other, backstab each other, and mock each other every chance they get. However, they do like to get together and pretend to be 'classy' ladies, boast about money, and plot together."

The Real Housewives of Beverly Hills season 5 reunion part 2 airs on Tuesday at 8 p.m. on Bravo. Below is a sneak peek at the upcoming episode.
