American rapper Cardi B has announced the arrival of her new baby boy with boyfriend Stefon Diggs.

The news was shared on Instagram alongside a video set to her song “Hello” from her Billboard 200-topping album Am I the Drama?, released in September 2025.

This marks Cardi’s fourth child. She already shares three children with ex-husband Offset: 7-year-old daughter Kulture, 4-year-old son Wave, and 1-year-old daughter Blossom.

In her Instagram caption, Cardi reflected on her journey, writing, “My life has always been a combination of different chapters and different seasons… A new baby into my world, and one more reason to be the best version of me, one more reason to love me more than anything else or anyone else, so I can continue giving my babies the love and life they deserve.”

In an Instagram Story, Cardi confirmed the baby’s sex, joking about a flower-covered stroller: “I just had a boy… why didn’t I know about this last year?”

Cardi and New England Patriots star Stefon Diggs first sparked relationship rumors last fall and made their first public appearance as a couple in May, attending the New York Knicks vs. Boston Celtics game during the 2025 NBA Playoffs.

The rapper also referenced her upcoming 2026 Little Miss Drama tour, which kicks off on February 11 in Palm Desert, California. “I’ve started prepping for tour, getting my body right, getting my mind right… I’ve healed, and I’m loving the woman I’ve become! That’s what this next era means to me, and I’m stepping into it better than ever,” she wrote.
