The Kardashian-Jenner clan is expecting three additions to their family and expectant moms Kim Kardashian, Khloe Kardashian and Kylie Jenner are all reportedly doing well.

Among the three "Keeping Up With the Kardashians" stars, only Kim, 36, has confirmed that she is expecting. However, multiple sources have verified that Kris Jenner's two other daughters, Kylie and Khloe are expecting too.

Kim who is expecting her third baby via surrogate is doing well. Her upcoming daughter is reportedly arriving in December or January and she is ready for it. In fact, she feels that she is at her best. "I'm, like, the most fit I've ever been," she told Allure via Us Weekly.

Meanwhile, in the next episode of "Keeping Up With the Kardashians," viewers will see Kim's reaction to her unflattering bikini photos. The mom-of-two explains in the teaser that aside from how the viewers perceive her body, she has anxiety attacks about her security and she is not comfortable with paparazzi snapping photos of her while on vacation.

On the other hand, Kylie, 20, is already four months along with her first baby with boyfriend Travis Scott. The pair who have never confirmed their pregnancy yet are reportedly talking about marriage already. A source told Us Weekly that Kylie is "keeping things sacred" and that the lip kit mogul is taking things day by day.

"Kylie and Travis have talked about marriage and baby names, but they don't want to jump into anything too quickly," the insider revealed.

Just like Kylie, her older half-sister Khloe is reportedly talking about marriage with Thompson too, but the pair is not in a hurry to walk down the aisle. "Khloe hasn't typically cared about getting married before having a baby," a source said. "She's open to it but it's not a prerequisite, to be married, before having kids."

Khloe, 33, is very happy with her bun in the oven. Those who have been following the family knew that she struggled to conceive with her ex-husband Lamar Odom. In fact, she sought fertility treatments but eventually stopped because their marriage at that time was already heading south.

Odom is wishing Khloe well now that she's expecting her first child. The NBA player confessed that he still got some love for his ex even after their divorce was finalized.
