Some even feel her butt is bigger than Kim’s!

Kim notoriously made headlines last week when she was photographed in a thong bikini while partying in Cancun for Kourtney Kardashian’s 38th birthday, and even lost 100,000 followers thanks to allegedly editing the pics on her social media accounts. The mother-of-two’s ass-ets got so much attention that fans of the famous family almost forgot about Caitlyn Jenner’s book promotion for The Secrets of My Life!

While some thought this was done as an attempt to sabotage the former Olympian, an insider exclusively revealed to In Touch that “making herself look bad isn’t the way she’d go about it. I can tell you that she’s not happy that what her butt really looks like is making headlines.”

We’re sure Kylie doesn’t mind being compared to the former sex tape star. At one point, she revealed she would love to “be” her older sister despite the stiff competition between them.

“I do want to be Kim,” she said on Snapchat in January 2016. “I think people forget that me and Kim are sisters. We’re not in a competition, we’re completely different people and Kim inspires me — 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.”
