If you hadn't already heard, hip-hop stars Soulja Boy and Chris Brown are planning a boxing match in the near future. Yes, really.

It seems that the two have already had a contentious relationship, but Soulja Boy has further stirred the pot in recent days by claiming that his beef with Brown began because he also had a relationship with Rihanna, and he tweeted that his motivation to beat Brown in the match was to avenge her beating at his hands in 2009.

The fight is being staged by Floyd Mayweather's Mayweather Promotions and is rumoured to be held in Dubai.

Mayweather is training Soulja Boy and Mike Tyson (yes, really) is training Brown - so of course, it stands to reason that Tyson should record a diss track and upload it to Instagram.
