Writing on his website, ThisIs50.com, a “disappointed” 50 reflected on Fab’s controversial Tweets.

“Reading what Fab said about me on Twitter was disappointing,” Fif wrote. “I have extended myself to Fab personally to allow him to expand himself as an international Touring Artist. I Thought we were Friends but that’s cool. Law #2: Never put too much trust in Friends, Learn how to use Enemies Be wary of friends–they will betray you more quickly, for they are easily aroused to envy. They also become spoiled and tyrannical. But hire a former enemy and he will be more loyal than a friend, because he has more to prove. In fact, you have more to fear from friends than from enemies. If you have no enemies, find a way to make them. –50th Law of Power. Am I 50 Cent or Am I Machiavelli? D*mmmm!!!”

Jay-Z defended rapper Kanye West in an interview conducted by DJ Trevor Nelson’s BBC radio show last week and irritated when Nelson suggested that West would not have stormed the stage at the 2009 VMA’s, had 50 Cent been an accepting an award instead of country singer Taylor Swift.

“No one is scared of 50 Cent. I want everyone to be clear. No one is scared of 50 Cent,” Jay-Z told Nelson firmly.

Although 50 Cent claims he does not have any problems with Jay-Z, he stated that no one would storm his stage.

“It wasn’t 50 Cent [who made the comments],” 50 told Angie Wednesday. “Hip-Hop has cool punk and Jay is the coolest punk in Hip-Hop. He’s big. And his take on it is [he’s] bigger than the art form and he won’t actually and compete. Battling has been a part of the culture.”

50 added, “When he [Jay-Z] has to say no one is scared of 50 Cent, it’s because the public is responding to his punk presentation. Kanye wouldn’t take the trophy from me and neither would Jay-Z.”
