American rapper, Cardi B, has announced the arrival of her baby boy with boyfriend Stefon Diggs, sharing the news through an Instagram video set to her track “Hello” from her chart-topping 2024 album Am I the Drama?.

The newborn is the fourth child for Cardi B — born Belcalis Marlenis Almánzar — who is already mom to daughter Kulture, 7, son Wave, 4, and daughter Blossom, 1, from her previous marriage to rapper Offset.

“My life has always been a combination of different chapters and different seasons,” she wrote in part of a lengthy caption.

“My last chapter was the beginning of a new season. Starting over is never easy, but it’s been so worth it! I brought new music and a new album to the world!

“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. This next chapter is Me vs. Me!”

Cardi also revealed the baby’s sex in an Instagram Story, admiring a floral stroller and joking, “I just had a boy … why didn’t I know about this (stroller) last year?”

The rapper and New England Patriots wide receiver Stefon Diggs were first linked last fall, but they didn’t go public until May, when they appeared courtside together at the New York Knicks vs. Boston Celtics game during the 2025 NBA Playoffs.

In her announcement, Cardi also nodded to her upcoming Little Miss Drama Tour, set to launch 11 February 2026 in Palm Desert, California.

“I’ve started prepping for tour, getting my body right, getting my mind right,” she wrote.

“There’s nothing that’s gonna stop me from giving you guys the performance of a lifetime! I’ve learned 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.”
