Alicia Keys and Lady Gaga take charity work seriously, and they're going offline to prove it.
Gaga, Justin Timberlake, Usher and other celebrities have joined a new campaign called Digital Life Sacrifice on behalf of Alicia's charity, Keep a Child Alive.
The entertainers plan to sign off from social media platforms like Facebook and Twitter on Wednesday, which is World AIDS Day. The participants will sign back on when the charity raises one million dollars.
"It's really important and super-cool to use mediums that we naturally are on," Alicia said.
For the campaign - which also includes Jennifer Hudson, Ryan Seacrest, Kim and Khloe Kardashian, Elijah Wood, Serena Williams, Janelle Monae and Alicia's husband, Swizz Beatz - celebrities have filmed "last tweet and testament" videos and will appear in ads showing them lying in coffins to represent what the campaign calls their digital deaths.
"It's so important to shock you to the point of waking up," Alicia 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 campaign, she said, puts the disease in perspective.
"This is such a direct and instantly emotional way and a little sarcastic, you know, of a way to get people to pay attention," said Alicia, who has more than 2.6 million followers on Twitter.
