This cowgirl recently posted this picture of herself from an elementary school yearbook to her Twitter page. Like many country yearbook photos, the key to solving this mystery girl's identity may be best found in the eyes, which still shine like polished chestnuts when she smiles.

The portrait was taken in the late '70s or early '80s, which should give you some idea of her age. The singer had her first radio hit in 1998 and quickly became one of the top female vocalists. In 2006, she competed for a short time on ABC's 'Dancing With the Stars.' These days, she tends to a very large family in addition to moving her music career forward.
