Cardi B has officially introduced her youngest child to the public, revealing both the face and full name of the baby boy she shares with NFL wide receiver Stefon Diggs. In an Instagram carousel posted on Wednesday, November 4, 2026, the Grammy-winning rapper celebrated her son turning one year old by sharing his first clear portraits alongside an emotional tribute. After keeping the toddler largely out of the public eye since his birth in November 2025, the 34-year-old artist confirmed that her fourth child is named Grey Marsean Diggs.

The birthday reveal was accompanied by glimpses of a themed celebration, custom diamond jewelry, and a playful nod to a long-running television medical drama that matches the one-year-old's initials. According to Billboard, a representative for the rapper confirmed via an official release that the toddler shares both his middle and last name with his father.

Inside the 'Grey's Anatomy' Photo Shoot and Birthday Tribute

In the November 4 Instagram post, Cardi B shared several images showcasing her son in different outfits. One set of photos captured the toddler wearing a green snapback hat paired with diamond chain necklaces and stud earrings, while another showed him dressed in a beanie and striped overalls.

The post also included snapshots of the boy's Halloween 2026 costume: miniature green surgical scrubs and a white doctor's lab coat, posed directly in front of a Grey's Anatomy logo to play on his initials, "Grey M.D."

Alongside the images, the rapper penned a personal message detailing how her pregnancy helped her navigate a turbulent period in her personal life. "Happy 1st birthday to Grey M.D!!" she wrote in the caption. "It's only been 1 year since meeting you but it feels like I've had you at my side forever. 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. I was growing you inside of me and at the same time you were giving me life!"

She concluded the note by playing on her son's moniker, adding, "You gave a new meaning to what a Grey day feels like.

You light up my life and every room with your smile your laugh and your precious spirit."

While the rapper's official caption and major entertainment outlets—including TODAY.com—consistently spell the child's first name as "Grey," at least one secondary report from Inkorr used the alternative spelling "Gray." Regarding the popularity of the chosen spelling, TODAY.com notes that "Grey" narrowly missed the Social Security Administration's top 1,000 baby names for boys in 2025, making it a relatively uncommon choice under that specific spelling.

Mickey Mouse Cakes, Balloons, and Custom Elliot Eliantte Jewelry

Beyond the portrait session, Cardi B gave followers a look at the toddler's birthday festivities through her Instagram Stories. According to Yahoo Entertainment, video clips from the party showed the one-year-old bypassing traditional photo poses to charge directly into a display of green balloons and Mickey Mouse-themed decorations, turning the party setup into a personal play area.

The celebration featured a green, multi-tiered custom cake adorned with Disney character details and large block lettering spelling out "GREY" and "M.D.," flanked by a smaller Mickey Mouse cake nearby.

True to her signature fashion sense, the rapper coordinated her own birthday ensemble around her son's name. As detailed by Page Six, she wore a monochromatic look featuring a silver wig, a heather gray tank top, gray manicure, and an Hermès Kelly Cut handbag in gray crocodile hide, which carries a resale market value of $70,000.

She completed the outfit with a frosted Audemars Piguet Royal Oak watch, two pear-shaped diamond rings, and three diamond necklaces—including a custom "Grey" collar, a tennis choker, and an emerald-cut diamond lariat necklace. On her wrist, she wore diamond tennis bracelets layered with custom bracelets crafted by celebrity jeweler Elliot Eliantte bearing each of her children's names.

The rapper previously used custom Eliantte jewelry in 2024 to publicly reveal the name of her youngest daughter, Blossom. The birthday reveal also followed months of subtle hints during which both Cardi B and Diggs wore jewelry spelling out "Grey," prompting fans to guess the moniker ahead of the official confirmation.

A Timeline of Cardi B and Stefon Diggs' Co-Parenting Dynamic

Grey is Cardi B's fourth child and her first with Diggs. The rapper also shares three children with her estranged husband, Offset: eight-year-old daughter Kulture, five-year-old son Wave, and two-year-old daughter Blossom. Diggs is also the father of two daughters from previous relationships.

Cardi B and Diggs first began dating in the spring of 2025 and made their relationship official on Instagram in June 2025. She announced her pregnancy in September 2025, and the couple welcomed their son in November 2025.

While TODAY.com notes that Grey was born on November 4, 2025, Billboard points out that the rapper first announced his birth to the public on November 13 last year. In those early weeks, she kept his identity tightly guarded, sharing only a brief glimpse of the infant swaddled in gear representing the New England Patriots, Diggs' NFL team at the time.

The couple's romantic relationship experienced public friction in early 2026. Following a breakup in February 2026, Cardi B addressed her relationship status onstage during a concert that same month, telling the crowd, "Just because I ain't f–king with my baby daddy doesn't mean you get to talk about my baby daddy." After a brief period of reconciliation and an on-again, off-again dynamic over the subsequent months, the two now appear to be focused strictly on co-parenting their one-year-old son.
