Jennifer Lopez revealed her abs in a cropped sweater yesterday as she shot her reality show Q'Viva! The Chosen. Jennifer joined some Argentine folk singers and dancers just outside of Buenos Aires as she looked for contestants to appear on the new TV talent competition, which she is co-producing with her ex, Marc Anthony. Jennifer has been increasingly taking on behind-the-scenes roles on both small- and big-screen projects. She just sold a pilot to MTV, and now Jennifer may star as Carmen Sandiego in a live-action film based on the character that she is already planning to produce. Her business savvy is just one of the reasons Jennifer was chosen as Glamour's Woman of the Year for 2011. The magazine also recognized the star for her philanthropic efforts and her signature style.
