Floyd Mayweather reignited his feud with 50 Cent with a savage Instagram post tearing into the rapper.
The unbeaten boxer has a long history of social media spats with the musician - who's real name is Curtis Jackson- and seemingly from out of nowhere launched an attack on him this weekend.
Mayweather, 42, took shots at 50 Cent's infamous battle with fellow rapper Kanye West when they released their 2007 albums.

He went on to lay into some of Jackson's business ventures and his declining record sales in a detailed Instagram post.
Mayweather wrote: "It was only four shots that ended Curtis Jackson rap career.

"You tried desperately to revive your career by going head to head with Kanye West and got dragged publicly, taking a unanimous decision loss.
"Jay Z been killing the champagne game with Ace of Spade selling worldwide at premium prices for well over a decade, while Curtis got a bottle with a cheap chess piece on it that taste like shampoo.
"Beats by Dre headphones was a home-run smash, we all know that, but what the f**k was Curtis's SMS Audio headphones?

"That was some straight bulls**t the FEDs had something to do with. Those are snitch headphones, you can be in your car and hear the people's conversation in the vehicle next to you.
"Diddy got Ciroc and its still selling worldwide and you can't find Efen in no stores and it's well known the s**t taste like rubbing alcohol."
Mayweather then added: "50 Cent went from selling 15 million to 200,000 - you talking about career been over."
The American boxer last fought in 2017 against Conor McGregor and has plenty of time on his hands.

And he decided to put some of that to use this weekend by taking aim at 50 Cent.
Jackson responded on Sunday by saying he wouldn't be drawn into a spat, but then hinted that Mayweather couldn't read.
He wrote: "Tell Floyd I said he won he is the greatest of all time. and nobody I mean nobody can ever take that away from him what he's done with his life is amazing. I'm done with all of the back and forth. Now Can Someone Please Read This To Champ."
