Alicia Keys, Lady Gaga, and Justin Timberlake and other celebs will give up their digital life — Facebook and Twitter — starting Wednesday, December 1, in an effort to raise money for charity.

The Digital Life Sacrifice event will raise money for Alicia’s charity, http://keepachildalive.org/" target="_blank" onclick="recordOutboundLink(this, 'Outbound Links', '/outgoing/http://keepachildalive.org/');return false; and raise awareness for http://www.worldaidsday.org/" target="_blank" onclick="recordOutboundLink(this, 'Outbound Links', '/outgoing/http://www.worldaidsday.org/');return false;. The stars will sign back online after the charity has raised $1 million.

“This is such a direct and instantly emotional way and a little sarcastic, you know, of a way to get people to pay attention,” Alicia told the Associated Press.

The celebs — including Usher, Jennifer Hudson, Ryan Seacrest, Kim and Khloe Kardashian, Elijah Wood, Serena Williams, and Alicia’s husband, Swizz Beatz — have also filmed “last tweet and testament” videos that show the stars lying in coffins.
