In June 2011, Hilson became an ambassador for MTV Staying Alive, a foundation which raises awareness and prevention of HIV and AIDS. In September 2011, she lent her support to US First Lady Michelle Obama's Let's Move! campaign, which aims to combat childhood obesity. She made T-shirts for the campaign that read "Pretty Girls Sweat", and exercised with the young women at The Educational Alliance's Sirovich Senior Center in New York City on September 24. During Hilson's visit in Africa in November 2011, she stopped by an orphanage to visit her young fans who had lost their families during the 2010–2011 Ivorian crisis. She gave each orphan a "care" package, which consisted of bookbags, T-shirts, sunglasses, notebooks and an electric keyboard. In April 2012, Hilson worked with DoSomething.org to encourage young people to take part in the nationwide Epic Book Drive by bringing books to local people in need. In a press release, she stated: "Joining DoSomething.org's newest effort to provide for people in need with Epic Book Drive was the easiest decision ever!. I truly believe providing access to those who want to learn is the key to bettering lives around the country. And helping kids find healthy outlets, such as books, has always been a passion of mine. So my involvement here is a natural fit."
