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 has been raised. The Digital Life Sacrifice is being organised by Alicia Keys' Keep A Child Alive charity for World AIDS Day on Tuesday.
Jennifer Hudson, Ryan Seacrest, Elijah Wood, Serena Williams and Swizz Beatz are also taking part.
They have filmed 'last tweet and testament' videos which will appear in ads showing them in coffins to represent what the campaign calls their digital deaths. Lady Gaga has more than seven million Twitter followers - while 3.5 million have signed up for Justin Timberlake's tweets.
World AIDS day, held December 1, is about raising awareness about AIDS caused by the spread of the HIV infection. AIDS had killed more than 25 million people between 1981 and 2007, latest figures have revealed.
