Cardi B has finally disclosed the name of her youngest child with Stefon Diggs. On November 4, 2026, on the first birthday of the child, Cardi announced the name as Grey Marsean Diggs. She shared photographs of birthday celebrations from Grey’s Anatomy-themed celebration on Instagram with a caption about motherhood.
Cardi B Reveals The Name Of Her Fourth Child
In an Instagram post on November 4, 2026, Cardi B wrote, “Happy 1st birthday to Grey Marsean Diggs!!” alongside photographs of her son’s birthday party.
In one of the pictures, Grey is shown dressed as a doctor with a Grey’s Anatomy-themed backdrop. Viewers have excitedly drawn a comparison between the theme and his name.
The caption revealed how she viewed the pregnancy, particularly juggling between her personal and professional life at the time.
"It's only been 1 year since meeting you, but it feels like I've had you at my side forever," she wrote.
She continued, "I carried you through one of the most uncertain high pressured times of my life but having you inside of me through it all gave me a extra strength."
The announcement came as a surprise for the fans because Cardi had previously declined to reveal the baby's name. In an earlier interaction with Highsnobiety, she promptly declined to share the name.
What does Cardi B's son Grey Marsean Diggs' name mean?
The name Grey has English origins and refers to the colour, often associated with balance, neutrality and sophistication.
Marsean, however, is an uncommon name, and its precise meaning or origin has not been publicly explained by Cardi B or Stefon Diggs.
Diggs is the surname of his father, NFL player Stefon Diggs.
Cardi also made a playful reference to her son's name in his first-birthday tribute, writing, "You gave a new meaning to what a Grey day feels like."

Cardi B and Stefon Diggs' Relationship: From Dating Rumours To A Reported Split
Reports of Cardi B and Stefon Diggs dating came in October 2024 when they were frequently spotted together in public spaces.
The first major public appearance which declared them a couple was on May 12, 2025, when they attended a New York Knicks playoff game at Madison Square Garden.
On June 1, Cardi made the relationship Instagram official with a series of pictures, including an affectionate photograph of the two together on a yacht.
Subsequently, in September 2025, Cardi announced her pregnancy during an interview with CBS Mornings anchor Gayle King.
"I'm having a baby with my boyfriend, Stefon Diggs," she said.
She also spoke about how Diggs had supported her while she prepared to release her album, Am I the Drama?. Cardi said he made her feel "very safe" and "very confident".
However, their relationship took an ugly turn when reports of a breakup emerged in February 2026. On February 9, Entertainment Tonight reported that the couple had recently separated.
Their fans also noticed that the two unfollowed each other on Instagram around the same time.
The reported split did not appear to be the end of their relationship. In May 2026, their appearance together at a Mother's Day event hosted by Diggs' Diggs Deep Foundation in Washington, DC, fuelled reconciliation speculation.
In June, speaking to TMZ, Diggs described Cardi as "beautiful" and said, "That's my child's mother. I love her to death." He also described their relationship as "great".
Neither has issued a definitive public statement confirming the current status of their romantic relationship.
