The Real Housewives of Beverly Hills airs Tuesdays (9 p.m. ET) on Bravo

Kyle Richards‘ tagline on this season of The Real Housewives of Beverly Hills is that she knows how to “spot a fake” — so we put her to the test.

PEOPLE Now recently caught up with the Bravo star, and she dished on the tagline and the two new Housewives that joined the cast this season.

“Well, you know, it’s kind of a funny story — a fan that I’ve actually never met came up with that tagline!” revealed Richards, 47. “She met a friend of mine in Oklahoma. So she came up with it, and I was like: ‘You know what? That’s perfect.’ I love it, and there are a lot of fakes in Beverly Hills and I am really good at spotting them, so I went with it.”

As for new additions to the cast, Richards said she grew particularly close to Dorit Kemsley.

“She entertains me — she makes me laugh, because things just fly out of her mouth,” said Richards. “She’s kind of like, a really good audience because everything I say, she dies laughing. Once we got to know each other, we really had a lot of fun together.”

Kemsley is definitely “very real,” added Richards. “I think there are times people are going to say: ‘Oh my God, I can’t believe she said that,’ but she’s not lying. She’s very honest, so I appreciate that in someone.”

Up next? Eden Sassoon, whom Richards cautiously calls an “interesting character.”

“I got the sense that she had seen the show because sort of zoned in on me and my relationship with my sister Kim, and I was sort of like: ‘Oh my God, no. Give me a minute. Let me get to know you,’ ” said Richards. “But she’s a good person. All in all, our entire cast are smart women and they’re good people. They sometimes say things they shouldn’t and make kind of bad choices — and I’m one of them! I’m not saying I’m excluded from that.”

So, is Sassoon real or fake?

“I don’t know, time will tell,” hedged Richards. “I think it’s real.”
