Alicia Keys says goodbye to Twitter

Well, not really. Alicia Keys is staying off Twitter until a million dollars is raised for her charity Keep a Child Alive.

Lady Gaga, Justin Timberlake, and other celebrities have joined the new campaign called Digital Life Sacrifice. The celebs plan to sign off of social media platforms, including Facebook, on Wednesday, which is World AIDS Day.

"It's really important and super-cool to use mediums that we naturally are on," Keys says.

Jennifer Hudson, Ryan Seacrest, and Kim Kardashian have filmed "last tweet and testament" videos and will appear in ads showing them lying in coffins to represent what the campaign calls their digital deaths.

Keys said recruiting celebrities was difficult because of scheduling, but "once I got people on the phone and I was able to paint the concept for them, everybody was in."

“Not one person said no,” she added.

With these celebs having million of fans following them, it will only be a matter of time before the million is reached. Think about it, Lady Gaga has more than 7 million followers on Twitter, and nearly 24 million fans on Facebook. If each of those fans donated $1, they could go way beyond their goal.

Fans will surely miss their favorite celeb tweets, but what a great way to use social media for a good cause!
