The Kardashians have always been in the tabloids for years now. A lot of the news they are in involves them having fights within their family, fights with other celebrities, divorces, marriages, and coming out of the closet.

The most recent tabloid news about them is a little eyebrow-raising to some people. Rob Kardashian was in a confession clip with his fiancée Blac Chyna for their reality show "Rob & Chyna" when an embarrassing confession was made.

It started out when the couple was discussing their childhood crushes, Rob teased Blac Chyna that she had a crush on Ricky Martin. The 29-year-old Blac Chyna took it lightly, giggled a lot, and even gave out her rendition of Ricky Martin's popular song, "Livin' La Vida Loca."

That did not stop Blac Chyna from taking a jab at her fiancé, she declared one of Rob's childhood crushes "Jennifer Lopez." Rob smilingly said, "Yeah, pretty accurate."

And then, things started to get weird. After saying J. Lo as one of Rob's crushes, she added, "Kim Kardashian..."

To which Rob blushingly said, "That is also pretty accurate." Blac Chyna then replied, "These are all facts!"

Several social media users were disgusted about this thought and were very keen on expressing it as well. Twitter user @laylajolie2 tweeted, "I knew Rob Kardashian is a weirdo, but not to the point where he admit that his sister Kim was his childhood crush."

According to sources, their family had a long-running joke that every male family member has a crush on Kim. One episode of the show "Keeping Up with the Kardashians" Brody Jenner tells Kris that Kim and his brother Brandon kissed back in the day.

Rob Kardashian never really said how young he was when he had a crush on Kim Kardashian. But regardless, the thought of having a crush on your very own sister no matter how old you were seemed to put off a lot of people.
