Christina Aguilera took a break from The Voice and promoting her new single, “Your Body,” on Wednesday to get political with Secretary of State Hillary Rodham Clinton at the George McGovern Leadership Award Ceremony. “Proud to use my voice for good & help,” Aguilera tweeted at the event, where the United Nations World Food Program Ambassador was recognized for her efforts in fighting global hunger. The U.N. and YUM! Brands Inc. together raised nearly $115 million for the U.N. World Food Program and other relief efforts since 2007.
