World AIDS day (December 1) raises awareness about AIDS caused by the spread of the HIV infection. Kim Kardashian poses dead in a coffin as she promotes the Digital Life Sacrifice, organised by Alicia Keys and her foundation, Keep A Child Alive, for World AIDS Day. Kim K, Lady Gaga, Justin Timberlake and Usher will quit social networking to raise money for the charity. They each will log off and not sign back into Twitter, Facebook, and their blogs until $1 million has been raised!
