Former heavyweight boxing champion Mike Tyson is to pen a tell-all memoir after signing a deal with publisher Blue Rider Press.

The sportsman-turned-actor will lift the lid on his rags-to-riches life, detailing his career in the ring, his stormy marriage to actress Robin Givens, and his jail sentence for rape.

The memoirs, which will be called Undisputed Truth and will be released next year (13), will be written in collaboration with Larry 'Ratso' Sloman, who has previously worked on Howard Stern's book Miss America.
