The million-dollar match will allegedly go down in Las Vegas this March. A mockup flyer posted to Soulja Boy's Instagram teases that the fight will go three rounds and be available on Pay-Per-View.
"It's going down! Signed my contract I'm leaving the fight with $1,000,000," the rapper wrote.
The flyer also reveals promotional involvement from boxer Floyd Mayweather, who Soulja Boy revealed to be his trainer in another Instagram video. Ever the instigator, 50 Cent has got in on the action by placing a $100,000 bet on a Soulja Boy victory.
As for Brown, he took to social media to write: "BOXING MATCH SET. Legally. Man to Man. NO MORE DISSING AND NO MORE BULLSHIT...THIS ISNT AN APOLOGY. IM TAKING RESPONSIBILITY FOR MY IGNORANCE."
The beef initially started bubbling when Soulja Boy liked and left a "heart eyes" emoji on a picture of model Karrueche Tran, who is also Brown's ex-girlfriend.
Tran herself wrote to Brown saying that she doesn't find the situation "Cool or funny...It's draining not just for me but for everyone. There's so much more out there in life then 'Twitter beefs.'"
On Soulja's end, the beef comes after a pre-holiday spat with Shia LaBoeuf, who may have just found himself a film angle to settle that score with.
