Cardi B fired back after her estranged husband Offset accused her of sleeping with someone else while she was pregnant with their child.

The 31-year-old called out her estranged husband Offset amid their impending divorce on Instagram Live Sept. 25. And the former Migos rapper took to the comments section to accuse the “WAP” rapper of cheating.

“U f–ked with a baby inside tell the truth!!,” Offset, whose real name is Kiari Kendrell Cephus, commented during the Live.

Cardi, who shares kids Kulture, 6, and Wave, 3, with Offset, most recently welcomed her third child earlier this month, featuring her ex in hospital room photos and videos despite filing for divorce in August.

Shortly after Offset’s comment, she wrote on X (formerly Twitter), “AND DID!!!!!!” which some fans online have speculated may have been her confirming Offset’s claim.

In her Live, the Grammy winner also went on to share that while she’s thankful for the former couple’s three kids together, she “regrets” him.

“But f–k you, I regret you,” she said. “I’m too good for you. I’ve always been too good for you.”

And the relationship between the two co-parents only seemed to get more tense.

“Since you wanna f–king threaten me, talking about you wanna take my s–t, you wanna take my s–t because I’m moving on?” Cardi said during her Live. “Move on. Move on. Why can’t you move on?”

“It’s no fun when Mama’s got the gun, right?” Cardi added. “Now we’re going to court war, right?”

E! News has reached out to reps for Cardi B and Offset for comment and hasn’t heard back.

The on-and-couple have a tumultuous history, with Cardi announcing in December 2023 that she’d been “single for a minute.” However, they reunited in public multiple times in the months since.

After ringing in the New Year together, Cardi clarified their relationship status, saying during a livestream, “The answer to getting back together is not a good night at the club and f–king the night long. We need to work on our s–t. We need to work on our communication. There’s things that he needs to work on, there’s things that I need to work on.”

In August, the “Bodak Yellow” emcee filed for divorce from Offset after nearly seven years of marriage, announcing her third pregnancy just later.
