Nicki Minaj has made a not-so-subtle casting decision that will, no doubt, reheat her beef with Cardi B ... despite the fact both superstar rappers are claiming it's squashed.

Nicki picked up where her homie Tekashi 6ix9ine left off by hiring the 2 strip club bartenders -- Baddie Gi and Jade -- who are preparing to sue Cardi. The women appear in the video for "Good Form" ... which features Lil Wayne.

The bartender sisters appear -- shaking their asses next to Nicki -- around the 40-second mark.

Yep, that's them alright.

Both Baddie and Jade posted screenshots on IG of their "Good Form" cameos and even got heart and kissy face replies from Nicki.

Nicki even shared a pic from the set with Cardi's foes in front of her.
