The ladies just got back from filming overseas in Amsterdam last week. Reality Tea reported that Rinna and Brandi Glanville are perhaps not getting along after their trip. The site said "Brandi apparently is jealous of Lisa's fabulous, happy lifestyle."

Rinna refused to answer any questions about the supposed feud at LAX when she arrived. Rinna has also reportedly not been getting along with Kyle Richards, but when asked about that feud, Richards wouldn't confirm anything. She said that's he doesn't have issues with Rinna or Glanville, "but maybe some others."

Real Housewives of Beverly Hills is currently filming its fifth season right now, although it doesn't have an air date yet."I can tell you we are very much in the middle of [filming]," Vanderpump told E! News. "The truth always comes out. Sometimes you have to wait a little while, then it comes out. The audience is smart. They see it."
