Kourtney Kardashian's little ones are growing up so fast!

Mason and Reign Disick—who share the same birthday—turned 7 and 2, respectively, Wednesday and received several special messages from their family.

The mom of three kicked things off with a birthday tweet, writing, "It is both of my baby boys birthdays today!!!"

Kris Jenner soon followed with an adorable Instagram photo of Mason and Reign. In it, the kids can be seen hugging each other, as Mason cuddles his little brother in his lap. "Happy birthday to these two sweet boys!! Our precious angels Mason and Reign. I love you more than words can say. #myheart," she captioned the snap.

According to People, Jenner also shared another birthday message on Kim Kardashian West's website and app, along with several photos that showed Kim cuddling her two nephews. "Happy birthday to my two sweet boys Mason and Reign who were miraculously born on the exact same day five years apart," Jenner wrote.

"You bring joy and happiness to me and everyone in our family and it is the greatest honor and gift in my life to watch you grow," added Kris. "I love you!!! — Lovie."

Khloé Kardashian also paid tribute to the boys on her website and app, posting a few adorable photos of them, including one that showed Kourtney giving Reign a kiss.

"Born to be besties!!! Happy birthday to the special boys who share the same birthday!," she wrote. "God blessed you with a sibling soul mate and I'm so thrilled to be your auntie. Watching you grow up has been one of the greatest joys of my life!"

Something tells us these two are going to have one serious birthday bash.
