Lisa Vanderpump is under fire on The Real Housewives of Beverly Hills due to Lisa Rinna's claims of her having manipulated her into speaking of Munchausen Syndrome and Yolanda Foster.

During the currently airing reunion, Rinna used phone records to prove she had been contacted by Vanderpump during filming, but according to Vanderpump, she wasn't contacting Rinna about their alleged story line. Instead, Vanderpump explained, she was texting her about their season six activities.

"In the weeks that we filmed, prior to the Munchausen exposè, arrangements were made between all of us," Vanderpump explained to fans in her Bravo TV blog last week. "LR's birthday dinner, the trip across the country to buy the little pony... I didn't want to go alone, and it was decided LR should come too. It was going to be a surprise for Ken and took quite a bit of organizing--the plane schedule, how we would execute our ridiculous plan, what we would wear, giggling over cowboy hats, etc. It was an interesting expedition, which certainly created much excited chatter between us."

"There was also Ken's birthday planning where LR and I went shopping for hats--something viewers didn't get to see--, Ken's actual birthday party, and I am sure other events and filming days, so of course there would be the odd phone call over those six weeks or so," Vanderpump continued. "Is LR alleging it was 10 conspiratorial conversations regarding YF? Absolute hogwash...I have 250 or so people that work for me, I organized endless events for this season, many events in the restaurants, worked tirelessly for Yulin, oh and filmed two reality shows consecutively. I have almost a farm at home, so I don't have the energy or time to focus on nonsense."

Vanderpump also defended herself against allegations of manipulating her co-stars on Twitter with the following re-tweet.
