After welcoming their third child earlier this month, the estranged couple had a heated exchange on Instagram and X (formerly Twitter) on Wednesday, Sept. 25

Cardi B didn’t hold back after Offset accused her of cheating on him while pregnant.

On Wednesday, Sept. 25, the estranged couple had a heated exchange on Instagram and X (formerly Twitter).

During an Instagram Live where Cardi (whose real name is Belcalis Marlenis Almánzar), 31, took jabs at Offset (whose real name is Kiari Kendrell Cephus), 32, her ex accused her of infidelity while she was carrying their child.

“U f–ked with a baby inside tell the truth!!,” he commented, per Hollywood Unlocked and E!.

Soon after Offset made that remark, Cardi commented on X, “AND DID !!!!!!,” which prompted fans to speculate that the rapper was confirming the Migos artist’s accusation.

On X, the “WAP” musician added that “A hurt Nikka will do the unthinkable,”

During her Instagram Live, the “Bodak Yellow” singer acknowledged how grateful she was to have three kids from their relationship, but she ultimately “regrets” her ex.

“But f— you, I regret you,” Cardi said. “I’m too good for you. I’ve always been too good for you.”

She added, “Since you wanna f—ing threaten me, talking about you wanna take my s—, you wanna take my s— because I’m moving on? Move on. Move on. Why can’t you move on?”

Cardi also seemed to imply that the former couple’s legal battle would be difficult.

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

Reps for Cardi and Offset have not yet replied to PEOPLE’s requests for comment.

Cardi and Offset, who share a daughter, Kulture Kiari Cephus, a son, Wave Set Cephus and a baby girl born in September 2024, have had an on-again, off-again relationship over the years.

The pair initially sparked romance rumors in February 2017 when they attended Super Bowl LI together. By October of that year, Offset proposed to the Cardi artist during Power 99’s Powerhouse concert in Philadelphia. However, it was revealed that this happened after Cardi and Offset had secretly tied the knot on Sept. 20, 2017.

The “Drip” performer has filed for divorce twice from the “Open It Up” artist — first in September 2020 and again in July 2024. Shortly after, Cardi announced on Instagram that she was expecting their third child together. Their baby girl was born just a month later.
