Random House is suing Sean "P. Diddy" Combs, claiming the hip-hop mogul failed to pay back a $300,000 advance for a memoir he never wrote. In court papers filed Monday, Random House says Combs agreed to "complete and deliver" the book back in 1999. "We now have waited for over five years and have received neither the manuscript nor the return of the money." Now that's my kind of deadline.
