Alicia Keys tapped The Beak, Kimmy Cakes, Ryan Seacrest, Usher and others to join her, her belly and her wedding ring in supporting Keep A Child Alive’s latest endeavor.

Each of the celebs poses with a barcoded shirt for the new Buy Life campaign, helping Keep A Child Alive continue their many initiatives agains HIV/AIDS in Africa and India. Here’s how the Buy Life project works:

When you buy life, you give life to millions of people affected by HIV/AIDS in Africa and India by providing the medicine, food and shelter needed to fight this awful disease.

Whenever you see a “BUY LIFE” bar code, simply scan it using Stickybits or WiMO and instantly make the purchase of a lifetime.

You can also purchase a fully scannable “BUY LIFE” t-shirt and invite others to buy life wherever you go. This shirt not only looks good, but every scan does the world good.

In other words, you can buy a shirt for $35, or you can scan someone else’s shirt and contribute as little as $10 at a time. Sounds pretty neat.
