Cardi B used Stefon Diggs Cardi B to introduce her youngest son, Grey Marsean Diggs, on November 4, turning his first birthday into the first public naming of the child. The post gave fans a first clear look at the family milestone after she had kept his name and face private.
“Happy 1st birthday to Grey Marsean Diggs,” she wrote in the Instagram tribute. The message did more than mark a birthday; it established the child’s full name in public for the first time and tied the reveal to a date that already had emotional weight.
Instagram Stories and Grey
Cardi B also shared clips from the birthday celebration on Instagram Stories, and the footage showed Grey heading straight for the balloons instead of posing for pictures. The party included green balloons, Mickey Mouse-themed displays, a green multi-tiered custom cake, and a smaller Mickey-themed cake nearby, giving the reveal a stage built around the child rather than the adults around him.
The cake carried large lettering spelling Grey and M.D., while Mickey Mouse details and character decorations filled the setup. That mix of names and imagery turned the party into a public identification moment as much as a birthday party, with the decorations doing some of the work that a formal announcement usually handles.
Grey Marsean Diggs in Private
Grey is Cardi B’s fourth child and her first with Stefon Diggs; she also shares three other children with Offset. The birthday post mattered because it reversed the privacy she had kept around Grey for months, replacing silence with a full name, a face, and a birthday scene that left little ambiguity about who the child is.
For readers, the practical takeaway is simple: the child’s name is Grey Marsean Diggs, the father is Stefon Diggs, and the birthday post is the moment Cardi B chose to make that family detail public. The story ends there for now, with the reveal carrying more weight than any follow-up tease could have.
