*Jamie Foxx and Chris “Ludacris” Bridges are joining other celebrities and African-American leaders to promote “i know,” a social media effort launched last week by the Centers for Disease Control and Prevention.

The celebrities, along with participating African-American organizations, will use their own Facebook pages and Twitter feeds to increase participation and expand the conversation’s reach.

“The ‘i know’ effort is part of CDC’s commitment to addressing the silence around HIV and inviting African-American young adults to take charge of the conversation,” said Kevin Fenton, M.D., director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention.

“At CDC, we have the science, but it is their voices that will make the difference,” he continued. “By supporting frank conversations through social media, ‘i know’ creates an opportunity for young people to talk directly with each other about the issues that fuel this still-deadly disease. Their ideas and involvement will be a critical part of the solution.”

Foxx will also star in a series of radio and online video public service announcements. In the PSA below, Foxx highlights the importance of talking about HIV: “We need to do something – all of us – and especially young people. We can start by talking about HIV with our partners, our family, our friends.”
