Boxing icon Floyd Mayweather Jr. has no problem letting people know he’s a walking legend. The sports mogul went online this week to flex major greatest of all time credentials.

On Tuesday, Money Mayweather hit up Instagram with a clip of himself putting in steady work during a boxing workout.

Recently, New York rapper 50 Cent clowned Floyd for his former girlfriends ultimately ending up with high-profile celebs.

“N*ggas keep calling my phone talking about, n*ggas took champ b*tch. Who? What you talking about? Talking about [boxer] Gervonta Davis done took champ b*tch. I’m like, I don’t know what the f*ck [is the big deal]. Nelly took one of them b*tches. Nelly took one of them b*tches. Now Gervonta done took one of them b*tches. He bought the b*tch a Bentley, Maybach. Condos and all that sh*t and now Gervonta got the b*tch. N*gga probably want to put a suicide note, man.”

It didn’t take long before Floyd struck back by trolling Fif with an article suggesting his baby mother accused him of having an STD.

Earlier this month, 50 Cent flamed Floyd over his fashion drip.
