Rapper 50 Cent has been offered the chance to settle his differences with former pal business partner Floyd Mayweather JR in the boxing ring for $5 million (£3.13 million).
The In Da Club hitmaker's friendship with Mayweather Jr crumbled earlier this year when their plans to set up a fight promotion company together fell through.
Last week, the rap star severed all ties with the sportsman amid claims Mayweather Jr had failed to fund the project - as agreed.
The two former friends took shots at one another on Twitter.com last weekend, trading insults after the sports star criticised his former partner's declining success as a rapper.
50 Cent responded by offering to pit his own boxer, undefeated Cuban Yuriorkis Gamboa, against Mayweather Jr in a big-cash fight, but now he has been offered an opportunity to step into the ring himself, according to AllHipHop.com.
Billionaire Alki David and his Celebrity Boxing business partner Damon Feldman have offered up $5 million to see the two stars spar for real, with the proposed fight consisting of three two-minute rounds and taking place in Las Vegas on 14 December.
The pair has yet to respond to the offer.
Feldman is the same guy who tried to entice Drake and Chris Brown into the ring for a charity fight night this summer after they were allegedly involved in a bar brawl over their shared affection for R&B beauty Rihanna.
