Are Kim Kardashian West and Kylie Jenner just trying to keep up with each other?

Kim took to the #FACTS section of her website on Friday to weigh in on her supposed "rivalry" with her 18-year-old sister, revealing she and Kylie laugh "so hard" when people pit them against each other.

"I think it's amazing," the 35-year-old reality star wrote. "There's no one else I would want to be in the same business with than my sister. She teaches me so much, and I teach her so much, and we're both so close that it's just funny."

"Sometimes I hear a rumor and I'm like, 'Wait, is that true?! What's really going on? I need to call my sister,'" Kim added. "But with this one, that has never been the case."

Kylie herself has previously opened up on whether she is trying to "steal Kim's throne."

"We're not in a competition. We're completely different people," she revealed. "She's one of my biggest inspirations. That's not a secret. I look up to my sister. I don't think that's a weird thing...I do want to be Kim."

Kylie showed off her Kim-esque booty --and got arrested! -- in a bizarre music video to promote her new lip gloss line. Check it out in the video below.
