Lady Gaga, Kim Kardashian, Usher, Justin Timberlake and more will kill off their cyberselves Wednesday (December 1st) as part of a Digital Life Sacrifice to promote World AIDS Day.

The idea was hatched by singer Alicia Keys to raise money for her charity, Keep a Child Alive, which provides money for medical care and support services for children and families impacted by HIV and AIDS in Africa and India.

The celeb participants have agreed to sign off all social networks on Tuesday until they raise $1 million for World AIDS Day. As part of the Buy Life promotion the celebrities will urge fans to donate to the charity in order to buy back their online presence. Fans can text the first name of the celebrity they are mourning to 90999 and $10 will instantly be donated to the cause.

Alicia told The Associated Press:

"It's so important to shock you to the point of waking up. 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. ... This is such a direct and instantly emotional way and a little sarcastic, you know, of a way to get people to pay attention."

Keys founded Keep a Child Alive in 2003, and on September 30, she and co-founder Leigh Blake launched Buy Life.

Of course, it's unlikely that Gaga and the others will be digitally deceased for long — Gaga has 24 million Facebook fans, and collectively, the celebs have nearly 29 million followers on Twitter.
