Cardi B escalated her feud with fellow rapper BIA on Thursday, using an X Spaces livestream to accuse her ex-husband Offset of sleeping with one of BIA's friends during his marriage to Cardi.

The blowup traces back to BIA's track "Sue Meee?", in which she revived rumors that Cardi cheated on Offset amid their much-publicized marital troubles. Cardi fired back on her own song, "Pretty & Petty," off her album Am I the Drama?, and the feud has only intensified since, according to Complex.

Cardi goes on the offensive

During Thursday's X Spaces rant, Cardi turned the cheating narrative back on BIA, claiming it was actually Offset who strayed — with one of BIA's own friends. "Let's talk about how months later your dumb ass told one of my ex-husband's friends that I was cheating on him," Cardi said, addressing what she described as a rumor BIA had spread previously, per reporting from iHeartRadio.

Cardi and Offset finalized their divorce after years of on-and-off separations. Cardi has since welcomed a baby with NFL player Stefon Diggs, and both she and Offset have otherwise moved on publicly. Neither Offset nor BIA had issued a detailed public response to Cardi's latest claims as of Friday.

The feud has played out almost entirely through music and social media, with both rappers trading increasingly pointed lyrics and live commentary over the past several weeks. Fans and industry watchers have speculated the back-and-forth could fuel additional single releases from either artist.

What's next

Neither camp has signaled the dispute is cooling off. With both rappers still actively promoting new music, further diss tracks — or on-air rebuttals — appear likely in the days ahead.
