To mark her first public performance and appearance since the tragic deaths in her family, Jennifer Hudson will be taking the stage at the Super Bowl next month to sing the national anthem. “She certainly can nail it,” a source tells E! News. “She proved it at the Democratic National Convention.” Jennifer sang the anthem when now President-elect Barack Obama accepted his party’s nomination in August. However, rumors that the singer would perform at the Inauguration are not true. Jennifer is up for four Grammys this year for her self-titled album.
