We’ve got the divorce docs and they spell it out clear as day: The couple IS expecting their third child together — and not just that, but #CardiB is demanding Offset cough up dough to help support their three kids.

Cardi B’s divorce filing from Offset just got a lot more interesting — ’cause we know now she wants her estranged hubby to cough up child support … including for their third baby.

TMZ has obtained the divorce docs — and they spell it out clear as day … noting the couple is expecting their third child together … and not just that, but Cardi is demanding Offset cough up dough to help support their three kids.

As we told you … she’s also seeking primary custody of the children — something that’s also confirmed in the divorce filing here. In terms of why they’re splitting … Cardi is citing irreconcilable differences, with no chance of patching things up.

One last thing that’s noteworthy about the docs … Cardi says she wants their personal property acquired during their marriage to be divvied up equitably.

There’s no explicit mention of a prenup in the docs … but that doesn’t necessarily mean they don’t have one.

As we’ve reported, sources with direct knowledge told TMZ the split wasn’t about cheating. It was just a case of two people drifting apart over time, with the breakup being a long time coming.
