Lisa Vanderpump is staying strong in her feud against fellow "The Real Housewives of Beverly Hills" star Brandi Glanville. During an interview with Star magazine via Radar, the 53-year-old reality star said Glanville was to blame for all the drama that takes place in Bravo's hit TV show. "It is just like every other false comment Brandi has made about me. Such as, I filed for bankruptcy, I live in the Valley, and that I got [houseguest] Cedric Martinez deported," Vanderpump said. "Just because Brandi says it, doesn't make it true -- and with her it is usually the opposite," she continued. But in spite of Vanderpump's claims, an insider tells Radar that Glanville isn't the only troublemaker on the show. "The driving force behind all this is Yolanda. She is the absolute ringleader!" a source said. "She just wants to create trouble for no real reason." "The Real Housewives of Beverly Hills" airs Mondays at 9\/8c on Bravo.
