As if starring in their own reality show isn't enough to get the attention of their fans, the Kardashian sisters have been hogging the spotlight for a few weeks, following the pregnancy announcement of Kim Kardashian-West (via surrogate), Kylie Jenner and Khloe Kardashian. The pregnancy news that came out one after the other have the fans wondering if this is all just one big coincidence, a conspiracy or some sort of upcoming 10th-anniversary of the reality show "Keeping Up With The Kardashians." However, it's worth noting that neither Kim, Kylie or Khloe have confirmed the pregnancies.

If anything, the confirmation of the pregnancies of the three Kardashian sisters has only been confirmed via their reps, otherwise known as a 'reliable source.' The father of Kylie Jenner's baby is said to be her current boyfriend, Travis Scott. Meanwhile, the father of Khloe Kardashian's baby is said to be her current boyfriend, Tristan Thompson.

Baby fever for the Kardashians

With the three Kardashian sisters expecting babies in 2018, the "Keeping Up With The Kardashians" family is definitely getting bigger. While this isn't the first baby for Kim Kardashian, the reality star is also experiencing a different first-time experience with the fact that this is the first time that she will have a surrogate.

Meanwhile, it is literally the first time for Khloe and Kylie to have their own babies growing inside them. Known for their sexy and svelte figures, a lot of fans are excited to see them sporting baby bumps of their own.

The surrogate theory

Ever since news about Kim Kardashian's surrogate being pregnant was released, many of the fans came up with a theory that Kylie or Khloe might be the surrogate.

Speculation grew because until now, the identity of Kim's surrogate hasn't been revealed, making the theory that one of the Kardashian sister's has volunteered to be a surrogate still entirely plausible.

However, if fans were to choose between Kylie and Khloe as the surrogate mother of Kim's third baby, the 20-year old makeup mogul would most probably have the majority of the votes.

Why? It's because her pregnancy was the biggest surprise since she is still so young. Meanwhile, Khloe is more mature than Kylie and openly talked about wanting to start a new family a few months ago. According to E! News, Khloe shared her thoughts on wanting to start a family on the finale of "KUWTK" season 13 finale.
