This is either a rumor or some of that FUD 50 cent likes to drop on the radio but supposedly he’s "purchased the rights to his baby mamas life story so she can never release a book about their relationship".
I’m not sure how that would work unless Shaniqua Tomkins agreed to it and they’re kind of having some issues right now. Even then he could only stop certain products, the story itself can come out in all sorts of legitimate forms, including interviews, and in such forms as thinly veiled novels and related fictional material.
From the out of left field department, I think a book of poems would be the perfect solution if this scenario were accurate. Something like, Remembering Marquise’ Daddy, with themes from thug love to baby daddyhood to surviving public humiliation and a related line of cards.
But I’m not really buying this one.

This woman really need to quit. this man clearly stated that he would get rich or die trying so this means that she didnt have anything to began with but now since the brother has an x-amount of money she just want except what he has already given to her and i know she has a nice piece of change from child support alone. that sister need to get over him cause he doing it big, she need to spend her time getting make-overs and spa treatments and quit bullshitting with herself cause money talk and bullshit (WALK).. and last but not never the least,love her son to the fullest and makae sure he’s physically and mentally happy.
