Stars Twitter Red for World AIDS Day

Ashton Kutcher, Liz Taylor, Queen Rania, Chris Rock, and other stars are turning their Twitter feeds red to support the (RED) campaign on World AIDS Day. Twitter and Facebook will also turn their sites red in collaboration with the (RED) campaign, which works with the private sector to raise money to fight AIDS in Africa, the region hardest-hit by the disease. Users can type "#red" after their Twitter messages to turn their tweets red, and Facebook users can turn their profile picture red to show their support.
