Kim Kardashian and Kanye West’s baby -- or twins -- are due to arrive in December. Days after announcing her second pregnancy in the midseason finale of “Keeping Up With the Kardashians,” E! News has revealed that the second baby is due to come around the holidays. The birthday could fall on the same day as Kourtney's kids, Mason and Penelope Disick. Other reports indicated that Kim may be carrying twins.

E! News reports that North West’s sibling(s) will be born on the same month as their cousins Mason and Reign. Kim’s older sister Kourtney gave birth to her first and third child on the same day five years apart. Both Mason and Reign were born Dec. 14 but were actually due around Christmas.

With Kim’s due date also falling near the holidays, it would not be impossible for her baby, or babies, to share the same birthday as Mason and Reign. That’s one big party waiting to happen for years to come if all three cousins will be born on the same day.

"It really has been a really long journey for us and we didn't think it was possible," said Kim. E! News caught up with her at the 2015 CFDA Fashion Awards last Monday. She was excited to talk about her pregnancy just after it was revealed on Sunday night’s midseason finale of “Keeping Up With the Kardashians.”

In the episode, she was shown going through several tests and fertility procedures. She had just about given up and even told her doctor that she’s exhausted and she’s had enough. The episode ended with the good news being announced in a sneak peek for the second half of the season.

Season 10 of “Keeping Up With the Kardashians” has shown Kim and Kanye’s struggle to conceive. The season kicked off with Kim’s admission that they have been having sex 500 times a day and she’s exhausted. Kim also underwent a minor surgery to clear her uterus. Her initial rounds of in vitro fertilization (IVF) didn’t succeed and just when Kim was ready to give up, she received the good news.

In the sneak preview for the second half of the season, Kim excitedly broke the news to her sister Khloe. She says that she got the blood test back and she’s pregnant. The gender of the baby, or babies, has not yet been revealed but more details are expected to come out when the reality show returns.

Season 10 of “Keeping Up With the Kardashians” is set to return this fall. The series airs at 9 p.m. EDT Sundays on E!.
