It is one of the greatest mysteries to ever challenge this planet.

No, I am not talking about who really killed JFK or, what lies at the center of the Bermuda Triangle. I am referring to the alleged pregnancy of not one, not two, but four, of the Kardashian/Jenner sisters.

For months it has been rumored that Kim, Khloe, Kourtney and Kylie are pregnant after some, fairly baseless, rumors began to circulate. Currently, the only confirmed Kardashian/Jenner baby on the way is the third child of Kim and Kanye, who is being born via surrogate.

Meanwhile, 38-year-old Kourtney has rubbished all rumors that she is expecting a child with her model toy boy of 10 months, Younes Bendjima. Kourntey, already a mother of three, called it a “crazy rumor” whilst proudly displaying her toned tummy in a crop top on The Ellen Show.

On the other hand, 33-year-old Khloe and 20-year-old Kylie continue to tease their fans with sly selfies and baggy clothing after both sisters were rumored to be with child. Kylie is reportedly pregnant with rapper Travis Scott’s baby, whom she started dating in the summer, but her ex-boyfriend Tyga has also appeared to claim paternity.

Khloe is supposedly expecting her first child with her NBA star boyfriend of roughly one year, Tristan Thompson. The couple are yet to confirm or deny the rumors. However, their sizzling Halloween costumes may provide the biggest hint yet…

Khloe looked sensational as she channeled Khaleesi Daenerys Targaryen from Game of Thrones, with a long bleach blonde wig and reems of (hopefully faux) fur. She accessorized her look with her 6ft7 basketball playing beau, who donned the costume of Khal Drogo.

Their choice of costume instantly garnered the interest of their fans, who believe that the couple consciously chose to dress as the Mother of Dragon’s and her temporary husband in order to hint towards their own personal predicament. In Game of Thrones, Khaleesi and Drogo have a child together, but the child tragically is stillborn.

For weeks, Khloe has been covering her tummy with her handbag, baggy clothing, and clever cropping of her images. However, this Halloween she seemed to forget all about her mission to hide her body as she squeezed into a barely-there outfit for Halloween.
