Cardi B Angrily Throws Pen After Asked About Offset-Stefon Diggs Triangle

2:53 PM PT — Cardi B is pissed and she’s letting the world know it, writing on X that she had to miss her kids first day of school to attend her civil trial.

Cardi B went from glowing to growling after leaving court on Tuesday after someone dared to ask if she was pregnant!!!

TMZ caught the wild exchange earlier today … someone off camera asked if she would predict any paternity drama with Stefon Diggs — in light of Offset apparently bragging he banged her up with Baby No. 4!!! 😬

Cardi didn’t take kindly to the question coming from a guy outside the Alhambra, CA courthouse, and threw a pen in a fit of rage … causing her bodyguard to call her back.

She retreated back to her vehicle but gave the guy a piece of her mind — respect women or else!!!

Earlier today, Cardi dodged the pregnancy question as she made her way into the courtroom … but still hasn’t flat-out addressed the situation since the speculation started.
