Boxing icon Floyd Mayweather Jr. has more money than even Uncle Sam can believe. The retired champion has hit up social media to show fans and critics alike how much cash he’s sitting on top of.

Floyd went to Instagram Friday (January 26) to make jaws drop with a $100,000,000 check.

Earlier this month, Mayweather’s foe Conor McGregor went to Instagram and trolled him.

In a recent interview, New York rapper 50 Cent said he’d beat McGregor in a street fight.

Right now, when he’s at 154 pounds?” 50 asked in response to a journalist’s question during a media conference call to promote his latest film, Den of Thieves. “I’m 225 right now! They don’t understand this is heavyweight [expletive] going on around here. I hit them, they see a white light. They hear a message. Slow down, boy. They think Jesus is talking to them.” He added: “Outside the confinements of the sport. If you got into a [street] fight, it’s a different thing.” (Express UK)

Last month, speculation developed about Mayweather possibly suiting up to fight in the UFC.

UFC and Floyd Mayweather Jr. are discussing a deal that would bring the undefeated boxer into mixed martial arts, according to UFC president Dana White. “We’re talking to Floyd about doing a UFC deal,” White told ESPN. “It’s real. He was talking about [boxing] Conor McGregor. Was that real? Have you heard Floyd talk about many things that aren’t real? He usually tips his hand when he’s in the media, and then that s— ends up happening. (ESPN)
