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.
