It seems like the Kardashian family is quite into celebrating their children's birthdays in the happiest place on Earth, in Disneyland. The Kardashians were again spotted at the festive park to celebrate Kourtney Kardashian's sons' birthdays, Mason and Reign Disick.

Apparently, Kardashian's sons, Mason who celebrates his sixth year and Reign his first year, share the exact same birthdates, Dec.14. And so, the mother of three, the birthday boys and her daughter Penelope, 3, all went to Disneyland and tried several rides along with other members of the Kardashian clan, the Daily Mail reports.

The publication even revealed that Kanye West, Kim Kardashian's husband, was present with their two-year-old daughter North West. However, Kim was absent since she just delivered her second baby, Saint West, and is recovering at home.

The famed momager Kris Jenner was also present and was very hands-on with her grandchildren. She was accompanied by her boyfriend Corey Gamble. The group was reportedly accompanied by other family members and friends and had tons of fun.

Before the extravagant trip to Disneyland on Monday, the family reportedly held an Alien-themed double birthday bash on Saturday with family and friends, Hollywood Life reports. The party featured a laser tag game, which friends and family of the Kardashian-Jenner clan enjoyed.

Photos even surfaced showing Kourtney wearing neon-colored glasses and guests were all given laser tag guns to join in the event. Of course, there were balloons in the form of aliens only for the celebration of Mason and Reign's birthday.

Both events in Disneyland and the Alien-themed party didn't have the boys' father Scott Disick, according to the Daily Mail. Scott has yet to comment, but Kourtney already shared her love for her sons on her Instagram account, posting an adorable photo of the brothers hugging while writing the caption, "Happy Birthday to my sweet boys who forever changed my heart! I still can't believe they have the same birthday."

 Happy Birthday to my sweet boys who forever changed my heart! I still can't believe they have the same birthday.

Furthermore, the 36-year-old mom also shared the story behind Mason and Reign's same birthdate. "It is still crazy to me that I have two boys born on the same exact day," Kourtney wrote in a new blog post on her website.

"I really tried to not have it happen, so they could each have their day, but there was no way around it. It is truly so special and meant to be. Happy birthday to the coolest and sweetest boys I know!!!" she added.
