G-Unit boss 50 Cent is either a fiend for the trolling or really has Conor McGregor under his skin. The New York rapper has publicly let loose on the UFC superstar – again.

Early Saturday, Fif went to Instagram to troll his pal Floyd Mayweather Jr.‘s August 26 boxing opponent.

Yesterday, 50 Cent exploded on Conor McGregor with some hard-hitting IG trolling.

👀what the fuck wrong wit this white boy, you fighting Floyd not me fool. LOL

A couple days ago, Conor sparked headlines after name-checking Fif and calling out his past financial woes at a New York media day.

Early during his press conference speech at Barclays Center in Brooklyn, McGregor (21-3 MMA, 9-1 UFC) took aim at 50 Cent, who has been known to be somewhat close to Mayweather (49-0 boxing), even walking out to the ring with him for previous fights. “What’s up New York City?” McGregor said. “50 Cent’s a b*tch. You and 50 are two fake money b*tches. He’s bankrupt, and you’re about to be.” (MMA Junkie)

Prior to the jabs, 50 had reacted to Conor blasting Floyd at their Toronto press conference.
