Cardi B has officially welcomed a newborn son -- her first child with NFL star Stefon Diggs -- marking a major new chapter in both her personal life and her expanding family.
The rapper shared the joyful news on Instagram, posting a video proudly showing off her post-pregnancy figure while reflecting on the transformation she's experienced over the past year.
In the caption, she wrote: "My life has always been a combination of different chapters and different seasons. 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," Cardi gushed.
"This next chapter is Me vs. Me! It's me against all odds me against everything meant to get in my way." The Bronx native continued, adding, "I've started prepping for tour getting my body right getting my mind right. There's nothing thats gonna stop me from giving you guys the performance of a life time!
"I've learned I've healed, and im loving the woman I've become! That's what this next era means to me and I'm stepping into it better than ever."
The arrival of her son adds to Cardi's growing family. As of November 14, 2025, she is now a mother of four: Kulture Kiari Cephus, 7, Wave Set Cephus, 4, Blossom Belle Cephus, 1, and her newborn, whose name has yet to be revealed.
This baby is her first child since her highly publicized split from ex-husband Offset, with whom she shares Kulture, Wave, and Blossom.
After years of on-and-off turbulence, the pair finalized their separation, allowing Cardi the space to rebuild emotionally and refocus both her artistry and her personal life.
Her relationship with Stefon Diggs began quietly, eventually becoming public as the two grew more serious, blending their worlds while maintaining a relatively low-key dynamic compared to her previous marriage.
Cardi's announcement underscores a sense of renewal: new music, a new era, and now a new baby grounding her as she prepares for an upcoming tour. For the rapper, this fresh start is both an emotional rebirth and a celebration of resilience -- a reminder, as she puts it, that she's "stepping into it better than ever."
