There could soon be a few choice words in the Beyonce-Jay-Z household. The richest man in rap has signed a megabucks deal to write a book on his life. I bet dinners in the dog will soon be staring an their house if he isn’t careful with his words..

It promises to be a warts-and-all account, which won’t impress his famously private wife Beyonce.

Says our bookworm: “It’s going to cover everything from his days on the streets as a drug dealer to his fairytale wedding to Beyonce.

“He’ll also be revealing his rapping secrets.”

He boasts of having spontaneous recording sessions, freestyling without writing his rhymes out first.

The book has no title or publication date yet but it will tie in with Jay’s next album, The Blue Print III, planned for September 11.

A few years back he shelved plans for an autobiography saying it was too personal and he wasn’t ready to share it with the world.

A spokesperson for Jay said: “It’s true. Jay-Z is writing a book.”

Hope he doesn’t get cold feet this time…
