The feud between rap rivals Rick Ross and 50 Cent has escalated - the IN DA CLUB hitmaker has helped his rival's ex-girlfriend launch a tell-all book.
The hip-hop star has been embroiled in a bitter war of words with Ross this year (09), with each MC looking for ways to discredit and humiliate the other.
50 Cent recently reached out to Ross' ex Tia Kemp - the mother of the rapper's son William Roberts III - and gave her a platform via his website ThisIs50.com to air her grievances about her relationship and custody issues with Ross.
Now 50 has helped Kemp land her own book deal - and she is revealing all in Tias Diary: Deeper Than Rap, which is set for release next month (May09).
The title references Ross' upcoming album Deeper Than Rap.
