The "Real Housewives of Beverly Hills" reunion show was taped on Friday and a new report claims that tension reached new heights after cast members confronted one another.
Fan favorite Lisa Vanderpump opened up about her tense relationship with former bff Kyle Richards and a source claims the pair got into a heated exchange.
"Lisa has been furious with Kyle all season for never defending her when the other ladies tore into her and it all came out on Friday!" A source told RadarOnline.com.
"They exchanged some very, very angry words but Lisa managed to keep it in check so she didn't come across as a catty b----," the source continued.
Season three addition Yolanda Foster, who is renowned for her level-headedness and calm demeanor, allegedly engaged in a dispute with Taylor Armstrong.
"Yolanda and Taylor also went at it, but it seemed totally forced, like they were playing it up for the cameras," the source said.
Adrienne Maloof, who refused to attend the reunion show after being advised by her attorneys, was at times the main subject of conversation. The newly divorced mother of three was reportedly concerned that she would be attacked by her co-stars.
"There was also a great deal of talk about Adrienne Maloof, who wasn't at the taping so couldn't defend herself at all," the source explained.
"Paul Nassif had plenty to say though! He had pre-recorded an interview that was played to all the ladies," the source went on.
Maloof has been embroiled in an ongoing feud with Brandi Glanville after the former model exposed a family secret. Glanville, who remained at the center of most of the drama throughout the season, was allegedly "quiet" during the catty reunion.
"Strangely, Brandi Glanville, who's usually the most outspoken of all the Housewives, was extremely calm, quiet and totally kept it together," a source said adding "I think she's sick of always being portrayed on camera as the crazy one."
