Birthdays are already a big deal in the Kardashian universe. Joint birthdays are practically a national holiday. On Sunday, Dec. 14, Kourtney Kardashian Barker and Scott Disick came together in spirit to celebrate a rare and heartwarming milestone for their two sons. Their eldest, Mason Disick, officially turned 16, while their youngest son, Reign Disick, rang in his 11th birthday on the very same day.
Kourtney Kardashian Barker, 46, marked the occasion with a touching post on her Instagram Stories. The Lemme founder shared a throwback photo of Mason and Reign from their younger years. “My birthday boys!! Two of the greatest loves of my life,” she wrote. The message resonated with fans who have watched Mason grow up since birth and Reign blossom into the family’s resident ball of joy.
Scott Disick Keeps It From the Heart
Scott Disick, 42, also chimed in with his own birthday love. He reshared Kris Jenner’s tribute to the boys on his Instagram Stories and added a heartfelt note of his own. “Happy birthday, my boys! You make my life better each and every day!” For followers who have watched Scott evolve from party boy to devoted dad, the message hit just right, as it reflected how central Mason and Reign are to his life today.
Grandma Kris Gets Poetic
No Kardashian birthday is complete without Grandma Kris stepping in with a beautifully worded tribute. Kris Jenner, 70, celebrated both grandsons with individualized praise that felt lovingly on brand. She described Mason as “such a kind, thoughtful, creative, and confident young man,” while honoring Reign for bringing “so much joy, laughter and light wherever you go.”
Fun Kardashian family trivia moment. Mason, born in 2009, holds the title of first grandchild of the entire Kardashian clan.
From Reality TV Baby to Teenager
Mason’s birth was a defining moment in reality television history. His arrival was filmed and aired during season 4 of “Keeping Up with the Kardashians,” marking a turning point for the series and for Kourtney herself. Reign arrived five years later on the exact same date in 2014. Unlike his older siblings, his birth was not filmed. Fans had to wait four months before finally seeing his first photo, which was released in April 2015.
Even then, Reign managed to keep a bit of mystery. Penelope Disick, now 13, joined the family in July 2012, completing the original trio Kourtney shares with Scott.
Kourtney on Motherhood and Growing Into Herself
On a recent episode of “The Kardashians,” Kourtney reflected on becoming a mom for the first time and just how unprepared she felt back then. “When I was 30, and I had Mason, nobody told me what to do, I didn’t read any books,” she shared in a confessional. Her instinct led her toward attachment parenting, something she later embraced more intentionally after reading about it before Penelope’s birth.
She also spoke candidly about work, motherhood, and choice. Back then, she felt working was nonnegotiable. Now, she feels grateful to have the freedom to choose what truly aligns with her life.
A Big, Blended, Birthday-Loving Family
Today, Kourtney is also mom to son Rocky Thirteen, 2, with husband Travis Barker. She is stepmom to Barker’s three children, Alabama Barker, 19, Landon Barker, 22, and Atiana De La Hoya, 26.
Kourtney and Scott first met in 2006 and dated on and off until their split in 2015. While their romantic chapter closed, their parenting partnership continues to evolve.
