Alicia Keys, Usher, Jennifer Hudson, Janelle Monáe and Justin Timberlake deliver their last tweets and testaments before signing off social media. The celebrities are sacrificing their digital lives on Twitter and Facebook to benefit Alicia’s Keep a Child Alive foundation, which raises money for HIV/AIDS in Africa and India. Once $1 million is accumulated, they will return to the social networking services. You can buy their lives back by donating at buylife.org.
