Cat fight in the Hills!

Denise Richards and Lisa Rinna really get into it on the latest episode of Real Housewives of Beverly Hills! The two actresses get in a cat fight after Rinna asks a question Richards felt was in poor taste.

It all started when Rinna and Richards attend a dinner party with co-stars Kyle Richards, Sutton Stracke, Dorit Kemsley, Teddi Mellencamp and Erika Jayne.

During the dinner party, Rinna asks Richards what is was like filming the threesome scene in the film The Wild Things.

"It’s uncomfortable,” the actress said. “It’s weird, but you have to just commit.”

She then added in a confessional, "I was raised in a very conservative family and went to church every week. … I was a good Catholic girl. My mom was the one that actually said, ‘If you feel this is something that you want to do for your career, then you just do it.’”

Rinna then took it a step further asking Richards if she would let her children watch the film, adding other personal questions regarding her parenting.

“You have to f--g own it, is really what I’m trying to say, Denise. You can’t be a hypocrite,” Rinna said to Richards. “Do you talk about the hookers around your kids? About the hookers that Charlie brings around? Because you’ve been quite free with us.”

Angered, Richards claps back, "Privately. I’ve had private conversations with them.”

Richards later said to the cameras that she doubts the friendship she's held dear with Rinna, saying, "Wow. This is my friend of 20 years? She knows I’ve protected these kids all these years."

She continued, "I don’t know if she’s trying to embarrass me or humiliate me, I don’t know. I don’t know what her agenda is, but whatever it is, it’s f--g hurtful.”

Richards and Sheen divorced in 2006, and have been co-parenting their two daughters Lola and Sami.
