Rick Ross: I Got Adrien Broner's Back ... New 'Money Team'

Rick Ross seems to be taking sides in the Floyd Mayweather vs. Adrien Broner beef -- partying with Broner in Miami this weekend ... and TMZ Sports has the footage.

It's interesting ... considering Ross had MAJOR beef with Floyd in the past -- but they seemed to bury the hatchet a few years ago.

Now, with Broner and Mayweather seemingly at war ... Ross seemed to make a pretty statement by allowing Broner into his VIP section at LIV nightclub on Sunday, where he kicked it with DJ Khaled and Lil Wayne.

FYI -- the beef between Ross and Floyd was SUPER HEATED back in the day, with Ross dropping a major diss track ... saying things like "f**k Floyd Mayweather" and calling him another word for a cat.

Ross sent Floyd $10,000 worth of champagne before the Pacquiao fight -- leading many to think the feud was over -- but now that he's hanging with Broner ... should we expect a new diss track??
