Lady Gaga, Alicia Keys, Justin Timberlake, Usher are going to sign off Twitter, Facebook and other social media – all in the name of charity.

The celebs are part of a new campaign called “Digital Life Sacrifice,” which is set to raise money on behalf of Keys’ charity, “Keep a Child Alive.”

On Wednesday, which is World AIDS Day, the stars will leave their millions of fans on various social media platforms, only to return when $1 million is raised.
