Madonna is once again making headlines on her "MDNA" Tour. This time it is for her recent concert stop in New Orleans where she told audience members to "vote for Obama" and was booed. The comment also triggered walkouts by several concertgoers, according to The Associated Press. The legendary pop star reportedly told the crowd at the October 27 performance after asking who was registered to vote, "I don't care who you vote for as long as you vote for Obama." President Barack Obama is the Democratic candidate of the 2012 presidential election and is running against Republican candidate Mitt Romney, the former governor of Massachusetts. "Seriously, I don't care who you vote for ... Do not take this privilege for granted. Go vote," she later added. So far on her "MDNA" Tour the singer has been sued in Russia for supporting gay rights during a concert, shown a swastika superimposed on French political leader's forehead and covered Lady Gaga in concert. A few fans at her Colorado show also complained she used a fake gun to shoot a masked gunman in a recent concert act in Denver, according to The Associated Press. Earlier this past summer, a gunman shot and killed several people during a midnight screening of a film in a movie theater in Aurora, Colorado. Madonna is not the first musician to support President Obama. Bruce Springsteen performed and spoke at two pro-Obama rallies last week. Meanwhile, rocker Meatloaf endorsed Mitt Romney.
