Is the insanely-secretive Jay-Z is planning to tell all about his marriage in a new book?

The acclaimed rapper is set to pen an autobiography in which he will open up about his life with wife Beyonce Knowles, despite their pact to never speak publicly about their relationship.

“It’s going to cover everything from his days on the streets as a drug dealer to his fairytale wedding to Beyonce,” a source told Britain’s Daily Mirror Wednesday.

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