Kourtney Kardashians has not one, but two birthday boys.
The Kardashians star celebrated her and Scott Disick’s sons Mason Disick, 15, and Reign Disick, 10, on their birthday Dec. 15 with a tribute looking back on their bond. Among the adorable photos was Mason carrying his little brother on his back and followed with snaps of the boys in matching pajamas as they pose with Kourtney as well as solo shots from their respective toddler years.
“My birthday boys,” the 45-year-old—who is also mom to daughter Penelope Disick, 12, with Scott and son Rocky Thirteen Barker, 13 months, with her husband Travis Barker—wrote on Instagram Dec. 15. “So special to me it hurts my heart.”
Kourtney wasn’t the only person keeping up with the birthday wishes.
Khloé Kardashian wrote in the comments, “I still can’t believe they are born on the same day,” with Kim Kardashian adding," Happy Birthday Mason and Reign. I love youuuuuuu."
Kris Jenner—who the kids affectionately call Lovey—penned a sweet tribute to the birthday boys.
“Happy birthday to my two incredible grandsons, Mason and Reign! Our birthday twins!” she wrote in her post. “I still can’t believe the two of you share the exact same birthday. What a special blessing that connects you forever. You are both so deeply loved, and I am endlessly grateful to God for choosing me to be your grandma.”
Kris went on to celebrate the boys individually.
“Mason, you are so kind, creative, smart, talented, and the best brother, son, grandson, cousin and friend,” she wrote. “Watching you grow up and become such a caring and wonderful young man is pure magic—you make us all so proud. Reign, you bring so much energy, laughter, and joy wherever you go. Your inquisitive mind and vibrant personality light up every room. You’re smart, funny, and full of so much love, and I feel blessed to witness the amazing little person you’re becoming.”
“You fill my life with so much pride and happiness, and I love you both with every bit of my heart and soul,” she continued. “I’m so proud of the incredible boys you are and excited for the amazing futures you both have ahead of you!”
In addition to the sweet birthday wishes, Mason also got a show-stopping gift from his dad. A mini version of the Mercedes-Benz G-Class Wagon.
"Happy birthday big boy!" Scott, who celebrated Reign’s birthday with a trip to a Los Angeles Rams game, wrote on his Instagram Stories, alongside a photo of the smaller vehicle parked next to several other cars. "Felt like it was only fair 4 you 2 get your first g wagon even if it’s a mini g wagon it’s still a wagon! Love u son!!!!!! Let the good times roll."
The 41-year-old added, "Gotta be the coolest little wagon I have ever seen! You deserve every inch of it! Love you more than anything in life."
