New York: Pop diva Lady Gaga, reality star Kim Kardashian and other celebs are sacrificing their digital life for a day to support a cause.
A campaign `Buy Life`, on the upcoming World AIDS Day, will see many celebrities stay away from social networking sites Facebook and Twitter.
They will remain away for one whole day until their fans donate up to USD 1 million for the cause, reported New York Times.
"Kim Kardashian is DEAD," reads the text in the advert, accompanied by the star`s photo featuring in a low-cut sequined burial outfit suggesting she "died" after a night out.
"Kim sacrificed her digital life to give real life to millions of others," it reads, asking fans to "visit Buylife.org or text `KIM` to 90999 to buy her life now."
Other participants include David LaChapelle, Justin Timberlake, Usher, Serena Williams and Elijah Wood, who are believed to have nearly 29 million fans on Twitter alone.
"Come on, y`all," actress Jennifer Hudson says in a videotaped plea. "Buy my life back. Go on a shopping spree and buy as much of it as you can."
The initiative is a part of singer-songwriter Alicia Keys` charity `Keep a Child Alive` which helps children and families affected by HIV and AIDS in Africa and India.
"It`s really exciting. No foundation has used the technology before like we are," the 29-year-old R&B star said.
The strategy is not to shock people into paying attention but to enable them to give by doing, "what you always do," Keys added.
