Be careful with her.

Cardi B eviscerated Stefon Diggs in a scathing concert rant during her Little Miss Drama Tour — just weeks after their highly publicized split.

“It’s called the principle. You can’t be out here playing with a bitch like me. There’s n—-s out here praying for a bitch like me. You hear me?” the “WAP” rapper said during her San Francisco tour stop on Feb. 27, per a video shared online.

“I’m too sexy to be lonely and too grown to be played with,” Cardi, born Belcalis Almánzar, added.

“You ain’t never had a bad bitch like this, n—a. Never in your motherf–kin’ life! None of them bitches ain’t f–kin’ with me!”

Page Six has reached out to Diggs for comment but did not immediately hear back.

Cardi’s rant came weeks after she and Diggs called it quits “a few days” before his NFL team, the New England Patriots, were defeated by the Seattle Seahawks in Super Bowl 2026.

The Grammy winner called it quits from the athlete as he allegedly “betrayed her so many times.”

“Her friends have been trying to show her that he is not right for her and that she deserved better,” a source told Us Weekly last month.

Cardi, 33, is now “single and putting herself out there again,” the source shared, adding, “She feels free.”

Another source told People that the mom of four “pulled back” from her relationship with Diggs, 32, because she “couldn’t trust him.”

“Cardi is very no-nonsense. The second she felt that she couldn’t trust him, she pulled back to focus on her kids, her music and tour,” the insider claimed.

After the Super Bowl, Cardi and Diggs unfollowed each other on Instagram.

The “Hustlers” actress and the athlete first sparked dating rumors last February when they were seen spending Valentine’s Day together in Miami. 

That June, they went Instagram-official with steamy pics and videos from their Memorial Day yacht celebration.

Cardi and Diggs welcomed their son in November 2025.

The wide receiver also shares five other kids with five other women. Four of his six kids were born in 2025.

The “I Like It” emcee shares three other kids, Kulture, 7, Wave, 4, and Blossom, 1, with her estranged husband, Offset.
