Cardi B returns to the gym just days after giving birth to first child with Stefon Diggs

Cardi B is already back in the gym after giving birth to baby No. 4.

The rapper, who welcomed her and boyfriend Stefon Diggs’ first child together last week, was filmed working out at a New Jersey gym Thursday.

In a clip obtained by TMZ, the Grammy winner worked out in a black sports bra, matching leggings and white tennis shoes.

The 33-year-old worked out with trainers, according to the outlet, and only stopped for a couple of brief breaks.

Later that same day, Cardi told her Instagram followers that her little one had arrived.

“My life has always been a combination of different chapters and different seasons,” she wrote Thursday. “My last chapter was the beginning of a new season. Starting over is never easy but it’s been so worth it!”

Cardi continued, “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!” the songwriter added. “It’s me against all odds me against everything meant to get in my way.”

Cardi assured her fans she had already “started prepping for tour” and “getting [her] body right.”

She concluded, “There’s nothing thats gonna stop me from giving you guys the performance of a life time! I’ve learned i’ve healed, and I’m loving the woman I’ve become! Thats what this next era means to me and I’m stepping into it better than ever.”

The “Hustlers” star, who rocked a cropped and corseted puffer coat in the social media upload, is also the mother of daughter Kulture, 7, son Wave, 4, and daughter Bloom, 1, with estranged husband Offset.

The former couple’s third child was born after Cardi filed for divorce from the Migos member, 33, in July 2024, following six years of marriage.

Cardi was subsequently linked to Diggs — and the duo went public with their romance at an NBA game in May.

News broke of their baby on the way four months later.

The NFL player, 31, is already the father of a 9-year-old daughter named Nova, and he was recently confirmed as the father of daughter Charliee, 7 months, amid paternity suit drama.
