Last May, it was reported that Curtis Jackson, the rapper better known as 50 Cent, cashed in his 10 percent share of Vitamin Water manufacturer Glaceau to the tune of a staggering $400 million. (Coca-Cola bought the company for $4.1 billion). Just last week, a rep for the company actually told us that 50 only ended up making a small fraction of the quoted sum, but it now seems that his name is being attached to another insanely speculative rumor: according to reports, 50 is on the verge of signing a $300 million "branding deal" with Rupert Murdoch's MySpace.

Per the alleged 10-year agreement, 50 would move his G-Unit label to a new division of MySpace Records. MySpace owners News Corp. would also helm all of 50's touring and marketing operations, as well as give him a production studio for film and TV projects. And since half of the $300 million would be locked up in stocks, 50 would hypothetically become one of News Corp.'s biggest shareholders. The deal pretty much stops just short of allotting 50 full editorial control over the Wall Street Journal newsroom.

There are a few reasons to believe it's blatantly false. For one, neither 50 nor his people at Interscope nor anyone at News Corp. has confirmed anything. Then there's the fact that the site that broke the story, MediaTakeOut, once also claimed that rapper Nate Dogg had died, which turned out to not be so true. But 50 should nonetheless be thrilled that he's now worth $700 million in fake Internet rumor-mill money.
