If you want your favorite celebs to keep tweeting, you're going to have to pay up. But it's not what you think--Alicia Keys, Lady Gaga, Usher, Justin Timberlake and other Buzzworthy faves are signing off from their Twitter and Facebook accounts this Wednesday, Dec. 1 (World AIDS day), on behalf of Alicia Keys' charity Keep A Child Alive, which helps fight AIDS worldwide. The celebs will sign back on once the charity receives $1 million.

Also participating in the great sign-off are Khloe and Kim Kardashian, Jennifer Hudson and Janelle Monae, among others. To help promote the "Digital Life Sacrifice," which will see celebrities essentially experiencing a digital death, Kim Kardashian appeared in a controversial ad where she is pictured with her eyes closed in an open casket above the caption "Kim Kardashian Is Dead.""It's so important to shock you to the point of waking up," Alicia Keys said of her digital departure. No argument here.

Vowing a stay offline is definitely a new way to approach the AIDS epidemic, and we love to see celebs using their powers for good. Lady Gaga alone has more than 24 million Facebook fans, and all of the participating tweeters together have over 29 million Twitter followers. It's exciting to think about what all that follower power is capable of. Stay dead, guys! Well, just for a little while for charity.
