Kim Kardashian is Dead!

Kim Kardashian plays dead in a coffin as stars leave the web until $1m is raised for charity

Lying on her back in a coffin, Kim Kardashian plays dead in a new advert.

The reality star is promoting an internet campaign in which stars including Lady Gaga, Justin Timberlake and Usher will quit social networking sites to raise money for charity.

In an unusual initiative, a host of celebrities will log off and not sign back in until $1 million (£640,000) has been raised.

The Digital Life Sacrifice is being organised by Alicia Keys' Keep A Child Alive charity for World AIDS Day on Tuesday.
