Stars like Lady Gaga, Justin Timberlake, Kim Kardashian, Khloé Kardashian Odom, Ryan Seacrest, Usher, Alicia Keys and more!

The Digital Life Sacrifice event will start Wednesday, Dec. 1 and help raise awareness for World AIDS Day and also raise money for Alicia Keys' charity Keep a Child Alive.

"It's really important and super-cool to use mediums that we naturally are on," Keys told the New York Daily News. "It's not that people don't care or it's not that people don't want to do something, it's that they never thought of it quite like that."

Once the charity reaches $1 million through text message donations to help families with HIV/AIDS in Africa and India, the celebs will return to their Facebook and Twitter accounts. The stars have also reportedly filmed "last tweet and testament" videos to help promote the cause, with some even appearing in coffins.

Co-founder Leigh Blake told the Daily News, "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? Its about love and respect and human dignity." (eonline.com)
