Gretchen Wilson will serves as a spokesperson for earning GED diplomas in a new public service advertising campaign which aims to reach high school dropouts in their mid-20s. Wilson partnered with the Advertising Council and the Dollar General Literacy Foundation for the campaign. "People need the right tools to succeed and, at the very minimum, a major tool on the road to success is a high school diploma or GED," said Wilson. "This campaign will go a long way toward educating people on how to take that first step to make a difference in their lives and the lives of their families, and I'm honored to be a part of it." Wilson dropped out of school after the eighth grade at age 15 and received her GED nearly 20 years later at age 34. View photos from Gretchen Wilson's graduation party in 2008.
