- 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 Keys' charity, Keep a Child Alive. The entertainers plan to sign off of social media platforms like Facebook and Twitter on Wednesday, which is World AIDS Day. The participants will sign back on when the charity raises $1 million.
