Over the summer, Louisiana rapper Webbie claimed that 50 Cent lost a boxing bet to him… and owes him a cool $1 million.

Apparently, Fif never paid up, and now, Webbie disses him over the unpaid debt.

On a new song called “What I Been Thru,” off his recently released Money Good mixtape, he calls 50 Cent a “bitch,” while threatening to come get his money. “You owe me a million, don’t make me come get it / I’m telling you I’m serious,” he raps.

Webbie claims he bet 50 Cent that his boxer Yuriorkis Gamboa would take the first loss of his career during a title fight against Terence Crawford in late June.

He was right… and now, wants 50 to pay up.
