As you're probably well aware, the press tour for the much-hyped fight between Conor McGregor and Floyd Mayweather is underway. During a Brooklyn stop at the Barclay Center, McGregror set his sights on some hip-hop greats, invoking both Jay-Z and Mayweather's pal 50 Cent. The Irish warrior trollishly handed Floyd a copy of Jigga's 4:44, imploring him to study and learn how to create a "real empire."

McGregor then told him to pass the album along to 50 Cent, before unleashing his wrath upon the Get Rich Or Die Tryin' rapper. "50 Cent's a bitch!" cries McGregor. "You and 50 are two fake money bitches. He’s bankrupt, and you’re about to be."

It didn't take long for 50 Cent to fire off some shots of his own. Never one to shy away from a bit of trolling, 50 posted a few Instagram shots aimed at McGregor:
