Lady Gaga has climbed onboard a new campaign named Digital Life Sacrifrice on behalf of Alicia Keys’ charity, Keep a Child Alive.

The superstar will join a host of other celebrities in leaving social media websites like Facebook and Twitter on December 1st (World AIDS Day), until the charity raises $1 million.

A string of adverts are set to show videos of Gaga and the other celebrities lying in coffins to represent what the campaign is calling their digital deaths. 

The president of Keep a Child Alive said: "I have a feeling that Lady Gaga is going to raise it all by herself. She has more than 7.2 million followers on Twitter and nearly 24 million fans on Facebook. She's got a very mobilized fan base and that's beautiful to watch and she's able to draw their attention to these issues that are very important, you know, and that people follow it and act."
