Cardi B Names Son Grey M.D., Celebrates First Birthday
The star revealed the moniker for her fourth child, born during a period of personal challenge.
Cardi B has officially named her fourth child Grey M.D., a decision that reportedly marks a significant moment for the pop star and her family. This naming choice comes amid a backdrop of personal challenges, as Cardi B mentioned that Grey M.D.'s birth occurred during a time of uncertainty and pressure in her life 3.
The baby's first birthday was celebrated on November 4, 2026, marking a joyful milestone for the family 123. Grey M.D. is the first child of Cardi B and Stefon Diggs, who began dating in spring 2025 1. Cardi B announced her pregnancy with Grey in late 2025, and the little one arrived on November 13, 2025 1.
However, there is some dispute regarding the full name of the child. While Cardi B's representatives confirmed the name as Grey M.D., E! News reported that the full name is Grey Marsean Diggs 2. This discrepancy adds a layer of intrigue to the story, though both names seem to honor the parents' connection and the new addition to their family.
In addition to celebrating his first birthday, Grey M.D. also made an appearance on his first Halloween, where he dressed up as a character from the popular TV show 'Grey's Anatomy', adding a touch of whimsy to the occasion 2.
Stefon Diggs, who is 32 years old, expressed excitement about teaching Grey M.D. various physical activities, showcasing the father's eagerness to bond with his son 3. Despite the on-and-off nature of Cardi B and Stefon Diggs' relationship, they now co-parent Grey, maintaining a collaborative approach to raising their child 1.
During her pregnancy, Cardi B experienced some bed rest due to the weight of the baby, highlighting the physical demands of carrying Grey M.D. to term 2.
