Kyle Richards Just Dropped the Most Surprising Detail About Kathy Hilton

Kathy Hilton and Kyle Richards have come a long way in their relationship over the years, as we've seen the sisters go through their fair share of ups and downs to form a growing bond together on The Real Housewives of Beverly Hills. And there's no denying that Kathy has given us plenty of memorable moments on RHOBH, from her iconic catchphrases to her epic dinner parties.

Well, in case you ever wondered what it was like growing up with Kathy, Kyle recently took a walk down memory lane to reflect on unforgettable childhood moments with her sister, which she shared exclusively in an interview with Bravo Insider (clip above). The RHOBH cast member revealed some surprising, and iconic, of course, details about her sister's life, adding to the list of reasons why Kathy remains an RHOBH "fan favorite" to this day.

"I will say that she was a typical grumpy teenager," Kyle said in the clip, above, going on to explain how her sister made her presence known when she'd pick Kyle up from school. "She would show up at school with, like, her cut-off jean shorts that were super short, a tank top to here," Kyle said, adding, in part, "She would have these big beer can rollers in her hair — I think that's what they call them — like pink, purple, all these colors."

Kyle went on to share how Kathy was "always very funny" and revealed a fun fact about something she had Kyle do that is definitely a signature Kathy prank.
