Alicia Keys, Lady Gaga, Justin Timberlake and Usher are going dark.
All in the name of charity. The aforementioned foursome and others are signing off Twitter and Facebook Tuesday until they raise $1 million for World AIDS Day.
Keys' charity, Keep A Child Alive, is staging a campaign that will have celebs such as Lady GaGa, Justin Timberlake, and Usher signing off of all social media.
PEACE OUT: Donate money or Usher won't be back on Twitter!
The "Digital Life Sacrifice" will feature the stars' filming "last tweet and testament" videos which will show them lying coffins to represent their "digital death."
"It's really important and super-cool to use mediums that we naturally are on," Keys said. "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 direct, instantly emotional way, a little sarcastic too, as a way to get people to pay attention."
