Lisa Rinna reconnected with the new Real Housewives of Beverly Hills star Kathryn Edwards at fellow co-star Lisa Vanderpump’s restaurant. Lisa Rinna and Kathryn Edwards first met when Rinna starred as Billie Reed on Days of Our Lives back in the 1990s.

“She’s either sold her soul to the devil, or she has some sort of special cocktail that she drinks, because she looks exactly the same,” Lisa Rinna says.

When Lisa Rinna brought up O.J. Simpson, however, her conversation with Kathryn Edwards ended rather abruptly.

It was long rumored that Edwards’s ex-husband had an affair with the late Nicole Brown Simpson after she separated from O.J. Simpson in 1992. These allegations first appeared in Faye Resnick’s 1994 tell-all. Resnick has appeared off and on throughout the years on RHOBH.

On Tuesday night’s episode of The Real Housewives of Beverly Hills, in addition to Kathryn Edwards’s debut, the topic once again turned to the O.J. Simpson scandal, with Edwards saying she was upset that Lisa Rinna brought the topic up when the two reconnected.

Kathryn and her then-husband, Marcus Allen, were friends with O.J. Simpson and Nicole Brown Simpson. In 1994, after Nicole was murdered, Faye Resnick wrote a book, Nicole Brown Simpson: The Private Diary of a Life Interrupted. In the book, Resnick said Marcus had an affair with Nicole.

“Lisa Rinna is someone I have known for over 20 years, and although we hadn’t kept in contact over time, she’s always someone I enjoy running into. What I wasn’t happy about was that the first thing out of her mouth was O.J….really? OK, if that’s what you think when you see me, I guess I haven’t made much of any impression on you. Beside the fact that I don’t think Rinna ever saw me once with O.J., but whatever. I’ll give her new memories,” Edwards said.

Lisa Rinna wasn’t the only one to bring up the Nicole Brown Simpson affair. Kyle Richards also brought it up, much to Kathryn Edwards’s dismay.

Have Lisa Rinna and Kyle Richards induced unnecessary drama by bringing up a decades old topic to their newest cast member?

How might this all play out in upcoming episodes of RHOBH?
