Alicia Keys

Alicia Keys, Justin Timberlake and Lady Gaga are among the many celebrities who will relinquish their digital life Wednesday in an effort to raise money for charity, according to The Associated Press.

On Wednesday, which is World AIDS Day, celebrities involved in the Digital Life Sacrifice event will sign off social networking sites such as Facebook and Twitter to raise money for Keys' charity, Keep a Child Alive. The stars will sign back on after the charity has raised $1 million.

"It's really important and super cool to use mediums that we naturally are on," Keys told the AP.

The participants — including Usher, Jennifer Hudson, Ryan Seacrest, Kim and Khloe Kardashian, Elijah Wood, Serena Williams and Keys' husband, Swizz Beatz — have also filmed "last tweet and testament" videos that portray the stars lying in coffins.

"It's so important to shock you to the point of waking up," Keys said. "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."

The Keep a Child Alive program was created in 2003 in an effort to raise funds for families affected by HIV and AIDS in Africa and India.
