Don’t be surprised if this Wednesday, your Twitter feed is surprisingly silent. On December 1st, Lady Gaga, Kim Kardashian, Justin Timberlake, Jennifer Hudson and other celebrities have pledged to take a break from social media to draw awareness to World Aids Day, and specifically to Alicia Keys’s Keep a Child Alive campaign. “This is such a direct and instantly emotional way…to get people to pay attention,” the singer told the Associated Press. The stars will sign back on once the charity raises $1 million. To do your part, make a one-time $5 donation to Keep a Child Alive by texting 9099. The charge will appear on your next phone bill.
