re: Jay-Z becomes Hip-Hop's first billionaire.

I thought it was 50 cent with Vitamin water?

Edit with info:

"50 Cent was previously one of the world's wealthiest rappers, largely thanks to his minority stake in Vitamin Water. In 2007, the Coca-Cola Company acquired Vitamin Water from Glacéau for $4.1 billion.

According to The Washington Post at the time, "50 Cent was thought to have walked away with a figure somewhere between $60 million and $100 million, putting his net worth at nearly a half billion dollars."
