Singer and actress Alicia Keys hosted her fifth-annual Black Ball on November 13; the gala benefits Keep a Child Alive, an organization that serves children and families living with and affected by HIV/AIDS, USA Today reports.  

In light of the worldwide economic crisis, Keys said that asking for donations might be a challenge, but she was optimistic about raising funds for the cause.

“It's a difficult time for all of us, but due to our recent election, it's a hopeful time,” she said.  

Other celebrities joining Keys at the AIDS fund-raising event included Tyra Banks, Jessica Alba, Justin Timberlake and John Mayer.
