Stars including Alicia Keys, Lady Gaga and Justin Timberlake are planning their deaths in order to "Keep a Child Alive."

Starting on World AIDS Day, Wednesday, December 1, celebs participating in the "Digital Death" campaign will virtually die -- logging off all social media sites like Twitter and Facebook until their lives have been "bought back" and $1 million collectively has been donated to the Keep a Child Alive campaign. The celebs will direct their online supporters to their personal pages at where fans can donate to the campaign. Keep a Child Alive provides AIDS care, support, nutrition and love to children and families affected by HIV/AIDS in India and Africa, according to the organization.

"By generously donating their time for Keep a Child Alive, these artists are bringing much needed awareness to the millions of people actually dying in Africa and India from HIV/AIDS," Keys said of the campaign. "We 'die' so they can live! ... We're digitally dying to give real life. I love the shock of it all, the call to action that we can all participate in!"

Other stars who are participating include Kim Kardashian, Ryan Seacrest, P. Diddy, Usher, Jennifer Hudson, Serena Williams, Elijah Wood and many more.
