The line was wrapped around the block as fans stood around the Barnes and Nobles on 5th avenue, anxious to meet 50 cent at the book signing for "The 50th Law". 50 became a fan of Robert Greene after reading "The Art of Seduction" and "The 48th Law Of Power". 50 reached out to Greene a couple of years ago to suggest a collaboration and here they are pictured together at the signing and promoting "The 50th Law". We aren't even going to lie, this is a book we'd purchase. In other 50 news, rumors were going around that he was dissing Jay-Z in his new mixtape track "Flight 187." 50 explained about why he compared Hov to sitcom character Steve Urkel...

It was the glasses. They saw the glasses. I didn't Photoshop glasses on him. I think Jay is really conscious of his actual moves. He does those things to make a statement in different ways to create clarity that he doesn't have to be the way people want him to be. He can do what he wants. But [I wrote the song] out of the perspective of me mentioning things I thought were interesting."

Meh, even if50 would be dissing him hard, Jay wouldn't even respond. More flicks from the book signing...
