The "Redneck Woman" is finally a high school graduate at 34-years-old. Country singer Gretchen Wilson passed her General Educational Development exam in April and will walk across the stage in a May 15th graduation ceremony.

Gretchen told The Tennessean that her 7-year-old daughter was the real reason she finally finished school, saying, "I certainly don't want her to think you can be this successful without an education."

Wilson's first radio single, "Redneck Woman," spent five weeks at No. 1 on Billboard's Hot Country Songs chart and it earned her a 2005 Grammy. Her debut album sold 4.5 million copies.

Despite all her accomplishments, until now Gretchen was one of 20 percent of Tennesseans without a high school diploma. Wilson says she dropped out of school in ninth grade.
