While she's only 18, Kendall Jenner's modelling career has grown successfully. Apart from participating in various designer runway shows, she has been enlisted as well to become the face of several brands.

In a trailer for an upcoming "Keeping Up with the Kardashians" episode, Kim Kardashian is seen taking a swipe at her half-sister. Although she has been vocal of how proud she is of Jenner's accomplishments, reports about Kim's insecurity issues are still surfacing.

In the said trailer, Kim is seen discussing a shoe purchase with sister Kourtney. Kanye West's wife said that she wouldn't buy "her" a pair of shoes for she already "bought her a f**cking career." Is she pertaining to Jenner?

Things might not be easy for Kim lately because of her attempts to get pregnant. In the trailer, Khloe is likewise seen teasing Kim about her attempts to conceive. The trailer also shows a positive pregnancy test being held by an unidentified hand.

Khloe similarly fuelled the pregnancy rumors by sharing the photo of the test on Instagram. She captioned it, "Who's pregnant? Kim, Khloe, Kendall." Khloe said that "Miss Menopause" or Kris Jenner should be "ruled out of the equation."

Did Kim manage to get pregnant? After all, it has been reported that she and Kanye are actively trying to conceive baby number two. While some doctors have allegedly advised Kim that she wouldn't get pregnant again because North's already a "miracle baby," nothing would stop the power couple from trying.

If Khloe turns out to be pregnant, fans will be left wondering if the baby daddy is Lamar Odom or French Montana.
