Project: Formula 50
Beverage company Glaceau, best known for their products Smart Water and Vitamin Water, knew they had something when they discovered Fif was a fan. They signed 50 Cent to endorse Vitamin Water, offering him a minority stake in the company. Going one step further, they developed the Vitamin Water flavor, Formula 50, which may not give you rock-hard, shot-nine-times abs, but is still pretty good. When Coca-Cola bought Glaceau for $4.1 billion, 50 received the single largest lump sum any rapper has been paid for grape drink.
