Kim Richards and Kyle Richards have seemed to be in a pretty good place in their relationship thus far on Real Housewives of Beverly Hills Season 4. But will things remain peaceful between them throughout the season?

Kim appears on Watch What Happens Live this week, and she is asked how close she is with Kyle, given that they have had their issues in the past.

"My relationship with my sister today is great," Kim reveals. "It's good — it gets better every day. And we are sisters, so we're going to have our moments. We haven't had one for a while, so I get a little nervous sometimes — I hope it doesn't happen anytime soon. But y'know, we're doing wonderful today."

"There hasn't really been anything this season that would bring on a big argument, unless something happens over the holidays, which I hope not," Kim says with a laugh. "But we've really had a good season — on-camera, off-camera. We just continue to grow as sisters."

So what does Kim attribute their improved relationship to? "When we have an issue, we pretty much discuss everything," she says. "I'm pretty good about just saying it how it is."

We're thrilled that the sisters have grown so much over the course of the show, and we hope they continue the good vibes!

Do you think Kim and Kyle's relationship seems to be on a good path?
