Cardi B claims she's got dirt on a bunch of people -- including her estranged husband Offset -- that she's about to drop ... all because she says he's using bloggers to come after her.
The rapper hosted a session on X Spaces ... and, she fired off some shots at her soon-to-be ex-husband during the convo -- alleging he's actually consorting with online blogs to spread rumors about her.
Cardi then makes mention of her ex, ... claiming he's got a lot of blogger friends who are posting about her -- even though she would never do the same to him. Worth noting, she doesn't provide any physical evidence to back up these claims.
She starts rambling from there -- claiming she wants an apology from a couple people she doesn't name specifically -- but, bottom line, she's still clearly pissed at Offset ... so, their split is still anything but amicable.
