Cardi B has welcomed her fourth child.

In September, the I Like It rapper announced she was expecting a baby with her boyfriend, National Football League (NFL) player Stefon Diggs.

And on Thursday, a representative for Cardi confirmed to People that she had given birth.

"Cardi is healthy and happy," the spokesperson shared.

No further details, such as the infant's name or birthday, were given.

But earlier in the day, the Am I the Drama? artist referenced her growing family in an emotional message posted via Instagram alongside a video of her lip-synching the words of her new song Hello.

"Starting over is never easy but it's been so worth it! I brought new music and a new album to the world!" she wrote in the caption. "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 (sic)."

Cardi, real name Belcalis Almánzar, went on to emphasise that she's competing against no one but herself in the entertainment industry.

"This next chapter is Me vs. Me! It's me against all odds me against everything meant to get in my way. I've started prepping for tour getting my body right getting my mind right," the 33-year-old continued. "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."

Cardi and sportsman Stefon, 31, started dating in October 2024.

The music superstar also shares three children - daughter Kulture, seven, baby girl Blossom, 14 months, and four-year-old son Wave - with estranged husband Offset, 33.

Cardi officially filed for divorce from the Migos rapper in July 2024, but the split is yet to be finalised.
