Brooklyn rapper Fabolous called out 50 Cent on Twitter yesterday, and 50 has let it be known that he did not appreciate it. As we reported yesterday, Fab posted several tweets questioning 50's claims of having "united New York" at his 'Thisis50 Festival,' which went down at Governor's Island this past weekend.

Fab wrote, "It's interesting to see 50 Cent unite with NY artists when he's one of the reasons NY hip hop became so isolated & crumbled.. Do u agree NY??"

50 responded today via his website, Thisis50.com, saying, "Reading what Fab said about me on Twitter was disappointing. 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."


50 added a quote from his New York Times bestseller '50th Law of Power' book. "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."

While a simple phone call would likely have cleared up the entire thing, 50 ended his response on a lighter note, comparing himself to a 16th Century Italian philospher, "Am I 50 Cent or am I Machiavelli? Dammmm!!!"

Keep it online, fellas.
