We could have guessed that 50 Cent wasn't one to mess with on the playground but now, the rapper, who isn't shy about his rough childhood, is authoring a book about a teenager's path to becoming a bully, according to MTV.

The quasi-autobiographical book will be a first person narrative from the point of view of a playground bully as he journeys to find redemption. 50 Cent's latest literary turn -- he has also written an autobiography, 'From Pieces to Weight' -- is expected to be on shelves in January of 2012 with the title, 'Playground.'

"I had a strong desire to write 'Playground' because I wanted to explore how a kid becomes a bully," 50 Cent said in a statement. "I drew on events from my own childhood and adolescence, but was excited to see the story take on its own life. This book would have been very helpful for me growing up and now that I have a teenage son, it is my goal that this will have a positive influence on all teenagers."
