“She was a little taken aback, too,” Kyle explained. “So I don’t know. I don’t want to speak for Kathy or Kim.”

But the mother of four confirmed she would indeed be turning the pages of her sister’s tell-all.

“I’m going to have to read it,” she said. “I’m very curious, actually.”

Kyle and Hilton eventuallyresolved the conflict, with a source telling PEOPLE in October 2018 that they were “finally in a better place.”

“They’ve worked on their relationship and things have gotten so much better,” the insider said. “Kyle hated that they weren’t getting along. Kyle is so much happier when there is peace in her relationships with her sisters.”

On Wednesday, Kyle acknowledged that every family has their tales to tell.

“All I know is that, you know, every family has stories and I was very respectful when I didAmerican Woman,” she told PEOPLE. “And I always had said that, even though it caused contention in the family. So I’m assuming my sister, I’m hoping — I don’t know. We’ll see.”

Family dynamics aside, the reality star is focused on her partnership withKendra Scott.

“I’m very excited to be here hosting Kendra Gives Back,” she said. “Obviously, a lot of people know that I lost my mother to breast cancer and Kendra also lost a very good friend of hers to breast cancer. So duringGalentine’s Day, you can come in and buy a gift for your girlfriends and 20 percent of the proceeds will go to theBreast Cancer Research Foundation.”

“So you’re buying your girlfriend a gift because you love her, and you’re doing a good thing at the same time,” she continued. “I really appreciate Kendra and her brand because she’s all about giving back.”
