It was a circus on Monday night's The Real Housewives of Beverly Hills
– a real-life circus.
Kim Richards invited the wives to the Cirque School for a day of fun and fitness, where they started off doing aerial acrobatics and ended up at each other's throats.
"Let's do this right," Lisa Vanderpump said prophetically. "Let's put one of the girls in a cage with a tiger."
Richards, 49, and Yolanda H. Foster were the first two tigresses to tangle, when Richards called Foster out for interrupting her in the midst of her welcome speech: "Yolanda, you're being rude!"
"We got it," Foster, 49, said. "You're repeating yourself."
The next two in the ring were Kyle Richards and Brandi Glanville, whose feud continued from last week's lunch
at Carlton Gebbia
's home, when Glanville asked Richards about the cheating rumors
surrounding her husband, Mauricio Umansky.
"I feel like a piece of meat hanging at the butcher," Richards, 44, said, while dangling in mid-air, before Glanville, 40, told her how upset she was after being chased by the paparazzi while out with her two children.
Glanville said the photographers shouted at her: "What do you think of Kyle Richards calling you a bully?"
"I never said that," said Richards, who was then pressed by Vanderpump, 53, at a lunch following the Cirque School to Tweet that sentiment.
"It would be a really nice thing [to do]," said Glanville, a gesture that was rebuked by Richards who said, "I have been dealing with the biggest nightmare of my life."
Circus day also elicited a mighty roar from former Miss Puerto Rico Joyce Giraud, 38, who told Vanderpump she was abrupt when Giraud tried to fix her hair at Gebbia's lunch.
[Brandi told me] Lisa does not take constructive criticism," Giraud said to the group.
"I tried to give her some good advice, and she turned on me," Glanville said.
"Sometimes when I'm on my period, I can be a total bitch," Giraud said.
"So you're on your period now?" quipped Glanville.
