50 Cent has been ruthless in his beef with Ja Rule. At Ja Rule's last concert 50 bought 200 front row tickets to the show just so it would be empty. Now 50 decided to step up his level of petty. Sources say 50 is currently in talks to purchase the masters and publishing to all Ja Rule's hit records. The reports claims that 50 is negotiating directly with with Def Jam, who own the rights to most of Ja Rule's music.
