Former undisputed heavyweight champion Mike Tyson will train Chris Brown for his celebrity boxing match with Soulja Boy.

The 27-year-old singer and Atlanta rapper - who are embroiled in a bitter feud and have exchanged threats on social media - will take their fury inside the ring in March, and Mike has agreed to prepare Chris.

Rapper/ex-boxing promoter Curtis "50 Cent" Jackson arranged for Mike to help with Chris' training after he placed a bet for $100,000 with former five division world champion Floyd Mayweather Jr. - who is training Soulja Boy - that Chris will win and he posted a video on Instagram of the conversation between him and Mike.

In the video, 50 Cent said: ''Listen Mike, they say Floyd's going to be training Soulja Boy so I said I've gotta get Mike Tyson to train Chris Brown,'' and Mike responded: ''Yeah, Soulja Boy's gonna get f****d up!''

Chris also shared the video on his own Instagram page.

50 Cent added in another video: ''I kind of feel like Floyd wants to train him so he can beat me. I just got off the phone with Iron Mike Tyson and Iron Mike is going to train Chris Brown. Now this is going to be a show! When I put on a show I put on a show!''

Mayweather says his promotional company, Mayweather Promotions, will stage the contest.

Chris and Soulja Boy's feud kicked off after Chris vowed to fight the 26-year-old rapper - real name DeAndre Cortez Way - for liking a picture of his ex-girlfriend Karrueche Tran.

Soulja Boy then raged on Twitter and he also roamed the streets looking for Chris and attempted to entice him into a brawl before they announced their planned boxing match.
