50 CentAs the saying goes, the rich just get richer.

50 Cent, the man who made a reported $200 million from his deal with Vitamin Water, is now said to be in negotiations with the Rupert Murdoch founded News Corp for a reported $300 million.

According to ThisIs50.com, the deal would go into effect in 2009, in which News Corp would take a large stake in all aspects of the 50 Cent brand — including music, books, concerts, and his G-Unit label.

The deal would help launch the company’s MySpace Records, as 50 and his G-Unit roster would move under the label’s umbrella.

Sources say half the deal will be in stock, in which 50 Cent would become one of the largest shareholders of News Corp.

Also under the deal, 50’s online community, ThisIs50.com, would be acquired by News Corp, his touring would be marketed through and sold via the company, and would also include a G-Unit book deal, and music publishing for 50 and the artists under his label.

While the deal is still in the works, it is not expected to be finalized until next year, after the rapper fulfills his contract requirements with Interscope Records.
