Twitter streams across the world are about to lose some star power. On Wednesday Dec. 1st, celebs including Alicia Keys, Lady Gaga, Usher, Jennifer Hudson, Justin Timberlake, Kim Kardashian, and many more are taking part in the new campaign called Digital Life Sacrifice. The stars will sign off of social media platforms including Facebook and Twitter on behalf of Alicia Keys’ charity Keep a Child Alive.

The digital protest is intended to raise money on World AIDS Day, with participants signing back on to their respective social networking profiles when the charity raises $1 million.
