Despite that, the former couple are still getting divorced...

From TMZ

Cardi B and Offset put on a friendly front at their son Wave's birthday bash this weekend ... but TMZ has learned the rappers are still very much broken up.

Sources with direct knowledge tell TMZ ... Cardi and Offset's divorce is still on and moving forward, despite their recent reunion at DreamWorks Water Park inside American Dream in East Rutherford, NJ.

We're told the divorce remains an amicable one ... which is why they're OK being in the same space while celebrating their children -- including daughter Kulture, son Wave, and an unborn little one on the way.

Sources say there has never been a discussion about not being around the kids at the same time ... and that's thanks to their friendly co-parenting dynamic, on full display during Wave's 3rd birthday party.
