Several megastars including Lady Gaga, Justin Timberlake and Usher are temporarily quitting Facebook and Twitter to raise money for Grammy winning singer Alicia Keys’ Keep a Child Alive (KCA) charity ahead of the World Aids Day. Keep a Child Alive aids families affected by HIV/AIDs in India and Africa. It has six main treatment sites located in Kenya, Ethiopia, South Africa, Uganda, Rwanda, and India. Keys is the global ambassador of KCA.

All the participating celebrities have recorded their last tweet and testament. Leigh Blake, the president and co-founder of Keep a Child Alive, explained, “We’re trying to sort of make the remark: ‘Why do we care so much about the death of one celebrity as opposed to millions and millions of people dying in the place that we’re all from?’”

The celebrities will return to the social networks once $1 million has been raised. Lady Gaga is expected to make a significant impact thanks to her massive social base (nearly 24 million Facebook fans and more than 7 million Twitter followers). However, as Keys explained, “It just doesn’t have to be just because you’re a celebrity or something like that. It can be anybody.”
