Big stars like Justin Timberlake, Lady Gaga, Alicia Keys, Usher, Kim Kardashian and more have refused to Tweet in a new campaign until $1 million is raised for 'Keep A Child Alive Charity' to fight HIV/Aids.

The campaign is in support of national aids day which is today. The stunt is to raise awareness as the stars 'play dead'.

Lady Gagas last Tweet said: Lady G posted: "@ladygaga is dead. I will sacrifice my digital life to fight HIV/AIDS. No more tweets little monsters until we #BUYLIFE"

Kim Kardashian took things to the next level by having her picture taken in a coffin. Afterwards the pictures released freaked out family and close friends.

On the whole though this stunt has brought a lot of attention to the charity.
