Fiddy and business guru Robert Greene have penned The 50th Law, which promises to reveal “how the power game of success can be played to your advantage”.

With chapters such as “Turn Shit Into Sugar-Opportunism” and “Hood Economics”, it’s safe to say it will take a street-level approach to business when it’s published this autumn.

Publisher Andrew Franklin said: “Those who dismiss 50 Cent as a gangster should rethink, his continued presence in the Forbes rich list and entrepreneurial nous show there is a lot more to the man than his music.”

The Grammy-winner will launch the guide by taking part in a debate at the Oxford Union later this year.

Rappers like Greene. Both Kayne West & Young Buck have name-checked his 1998 business guide, The 48 Laws Of Power, in song.

The book urges budding business leaders to “conceal your intentions” and “crush your enemy totally”.
