Cardi B has finally revealed her youngest son’s name. The rapper shared the name Grey Marsean Diggs in an Instagram post on November 4, 2026, to mark the little boy’s first birthday — a full year after she welcomed him without ever saying his name in public.
“Happy 1st birthday to Grey Marsean Diggs!! It’s only been 1 year since meeting you but it feels like I’ve had you at my side forever,” Cardi wrote alongside a set of photos of her son.
The post also gave fans their first clear look at Grey’s face. Until now, Cardi had kept both his name and his face private since his arrival last November.
Who is Grey Marsean Diggs?
Grey is Cardi B’s fourth child and her first with NFL star Stefon Diggs, the New England Patriots wide receiver. He was born on November 4, 2025, so the birthday post landed exactly one year after his arrival.
Cardi first wrote his name in the caption as “Grey M.D.” — a nod to the tiny doctor’s costume he wore in some of the photos, complete with a Grey’s Anatomy sign from his Halloween pictures. A representative for the rapper later confirmed to Billboard that his full name is Grey Marsean Diggs, with both his middle and last name coming from his father.
The birthday photos show Grey in several outfits, including a baseball cap on a bed and the little surgeon scrubs that inspired the “Grey M.D.” joke. Cardi also shared clips on Instagram Stories of her son going straight for the balloons at his first birthday party.
Why Cardi kept his name private for a year
Cardi confirmed her son’s arrival on November 13, 2025, nine days after he was born, but she never shared his name or a clear photo of his face. She had announced the pregnancy in September 2025 during an interview with Gayle King on CBS Mornings, a few months after she and Diggs went public with their relationship in June 2025.
Grey is Cardi’s fourth child. She also shares daughters Kulture, 8, and Blossom, 2, and son Wave, 5, with her estranged husband, rapper Offset. For Diggs, Grey is his sixth child, according to Page Six.
In her birthday message, Cardi wrote about how much her son has meant to her during a difficult period, saying he gave her life — a line that fans quickly picked up on as the heart of the post.
What Cardi B has said about motherhood
The name reveal came in a busy year for Cardi. Her album AM I THE DRAMA? arrived in 2025, and she has spoken openly about balancing a major music career with raising four children. The birthday post was not a publicity stunt or a magazine cover — it was a personal Instagram tribute, which is why the name spread so fast once fans spotted it.
The timing also matters. By waiting until Grey’s first birthday, Cardi controlled the moment herself: the name, the photos and the message all came from her own account, rather than from a leak or a paparazzi picture. JustJared’s report on the birthday post notes she shared the news alongside the first clear photos of their son, while Revolt’s account of the first photos describes the carousel of pictures she posted.
What happens next
Cardi has not said whether she will share more photos of Grey or keep him mostly out of the spotlight, as she did for his first year. For now, fans finally have a name to go with the little boy she has been quietly raising — Grey Marsean Diggs.
