[artist id="1164800"]Fab[/artist], hip-hop's current Twitter king, started tweeting Tuesday morning (October 6) about Saturday's [article id="1622984"]ThisIs50 Music Festival[/article], during which the G-Unit united with some of their past foes, such as D-Block and the Diplomats.

"It's interesting to see [artist id="860639"]50 Cent[/artist] unite with NY artists when he's one of the reasons NY hip hop became so isolated & crumbled.. Do u agree NY??" Fab said in his first tweet.

He followed up, pondering, "I wonder if this is a law in the [article id="1621181"]'50th Law of Power' book[/article]? I guess it was a good show for New York.. But if you asked 50 a few years ago if he ever saw himself on stage with any of them, he would've said HELL NO!"

In another set of tweets, Fab made it clear his intention was not to dis 50, but to think aloud. "At 50's peak, his grind was unmatched, image was bulletproof, music was ignorantly motivational & catchy, even classic. Most never have that. ... So don't think I'm takin' shots at 50.. Just that NY show had me a lil' puzzled.. But I love NY so I couldn't knock it if I wanted to."

50 responded via his ThisIs50.com Web site, and he didn't take too kindly to Loso's words.

"Reading what Fab said about me on Twitter was disappointing," he said in a statement. "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."

Fif also included an excerpt from his aforementioned book, "The 50th Law of Power." "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."

50 ended with a joke: "Am I 50 Cent or am I Machiavelli? Dammmm!!!"
