Back in July, rapper 50 Cent tweeted a message with a very ambitious goal attached. "I want to impact peoples lives more. I created a new goal for myself, I want to feed a billion people in Africa over the next five years."

Everyone would likely agree and just chalk it up to another celebrity blowing hot air about changing the world, but last Friday, the 36-year-old (whose real name is Curtis James Jackson III) revealed a means to making his goal come true.

At the news conference, 50 announced he was teaming with Pure Growth Partners on a new energy shot called "Street King." For every shot purchased, the company will provide a meal to a child in need. The plan is to feed 1 billion children in the next five years.

"50 Cent and I share a common vision: to address the world's problems through smart and sustainable business models," Pure's CEO Chris Clarke said in a statement. "With the rampant starvation in Africa and hunger afflicting children worldwide, we need socially responsible businesses that affect real change now more than ever. And Street King can set the bar for future generations to come."

Added 50 Cent, "I'm inspired by [Clarke's] vision and innovative approaches to tackling serious issues. It's our mission with Street King to really change children's lives around the world."

It's really great to see 50 using his success in the energy drink world to impact the lives of others. It's estimated that he made $100 million from his previous partnership, "Formula 50" Vitamin Water drink with Glacéau.

Expect "Street King," which is free of carbs, calories and sugar, to hit nationwide in September, costing between $2.49 and $2.99.
