American rapper Belcalis Marlenis Almánzar, known professionally as Cardi B, has welcomed her new baby boy with her boyfriend, Stefon Diggs.

The rapper shared the news in the caption of an Instagram video soundtracked by her song “Hello,” from her Billboard 200-topping sophomore album ‘Am I the Drama?’, which arrived in September.

This is Cardi’s fourth child, following her trio of kids with ex-husband Offset, which includes her 7-year-old daughter, Kulture, her 4-year-old son, Wave, and her 1-year-old daughter, Blossom.

“My life has always been a combination of different chapters and different seasons,” she wrote in part in the 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!”

In a video posted to her Instagram Story, Cardi confirmed the sex of the baby, fawning over a girly, flower-covered stroller and lamenting, “I just had a boy … why didn’t I know about this (stroller) last year?”

While whispers of their relationship started in the fall of last year, Cardi and New England Patriots player Stefon Diggs made their first public outing as a couple in May, cuddling up courtside at the New York Knicks vs. Boston Celtics game during the 2025 NBA Playoffs.

In the Instagram caption, Cardi referenced her 2026 Little Miss Drama tour, which kicks off on 11 February 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.”
