The whole thing just means a lot to me personally," said Ben Affleck. "When you have a chance to make a difference, you do." The actor welcomed Dr. Faida Mitifu-the Democratic Republic of the Congo's Ambassador to the United States-and Rose Mapendo to the event before taking the stage to present CNN's Anderson Cooper with the International Medical Corps Humanitarian Award. 03 of 07 Malin Ackerman Alberto E.

"You need your closest friends around you," the actress said. "And a bottle of wine or two." 04 of 07 Marisa Tomei Jason Merritt/Getty Images Marisa Tomei couldn't resist the beat of the bongo drums, swaying to the sounds of the Congolese drummers who welcomed guests like Andie McDowell, Emanuelle Chriqui and Nia Vardalos to the House Of Blues. 05 of 07 Benji and Joel Madden Jason Merritt/Getty Images "I've actually gotten to see the International Medical Corps at work in the field, I got to spend the week with them.

"The situation in Central Africa is an issue that's close to my heart and I'd like to be a part of the solution." 06 of 07 Sheryl Crow Jason Merritt/Getty Images "Are we really going to party?" asked Sheryl Crow as she took the House of Blues stage after a round of inspirational speeches.

South African singer-songwriter Vusi Mahlasela also took a turn entertaining the crowd. 07 of 07 Alyssa Milano Jason Merritt/Getty Images "It's about trying to dissect and learn and let live and self-reflect so you can understand it," mused Alyssa Milano about the theme of the evening.
