The reality star joins celebs like Lady Gaga and Justin Timberlake in making a “Digital Life Sacrifice,” wherein they stop using Twitter and Facebook in an effort to raise awareness and money for Keep A Child Alive. Kardashian and others have shot provocative ads where they pose in coffins and have even filmed “last tweet and testament” videos. They will log off on Dec. 1 (World AIDS Day) and not sign back on until $1 million has been raised.

The event is organized by Alicia Keys, a global ambassador for the charity. Keys said no celebrity turned down her request to take part in the campaign. “Once I got people on the phone, and I was able to paint the concept for them, everybody was in,” she told UK’s Daily Mail.
