Mason and Reign Disick both turned 6 years old and 1 year old, respectively, on Monday, and mom Kourtney couldn't help but give her boys an adorable Instagram shout-out to mark the occasion. In a photo showing big brother Mason hugging Reign, she wrote, "Happy Birthday to my sweet boys who forever changed my heart! I still can't believe they have the same birthday."
