A few months ago Shyne threw a sloppy shot at 50 Cent on his freestyle over Alicia Keys' 'Un-Thinkable (I'm Ready).' The formerly incarcerated rapper called out 50, rhyming, "I need a couple million, f--- 50 Cents," but the G-Unit CEO didn't seem too keen on entertaining Shyne's beef. Instead, Lloyd Banks had 50's back, calling Shyne 'wack' for dissing his boss, but now it seems that the Queens rapper has finally decided to get his revenge.

Shyne hosted a live Ustream conference call with Def Jam Records on Wednesday (Aug. 11) and 50 decided to interrupt the session with a prank call -- Bart Simpson style. Naturally, 50 also recorded the entire episode, for our viewing pleasure. Watch 50 Cent dial into Shyne's Def Jam conference call, pretending to be a caller named Sean, who opens with the question, "What is your real issue with 50?"
