Celebrities are appearing in a series of adverts, which are featured in magazines throughout America.
Alicia Keys, Jessica Alba, Iman, Zoe Kravitz (Lenny Kravitz's daughter), Lisa Bonet and Indian model Padma Lakshmi pose for the ads in black.
This should happen all over the world ... not only in America and for the unfortunate people of Africa and India ... there are so many other poor countries and unfortunate children that need urgent help ...
