6. Faith Hill
On September 21, 1967, Faith Hill was born Audrey Faith Perry to unmarried parents in Mississippi, and adopted just a few days later by Ted and Edna Perry. Although her birth parents went on to marry and have a son, Faith was given a devout Christian upbringing by Ted and Edna, who had two biological sons of their own. Faith, who always knew she was adopted, began her singing career in churches and local rodeos. Her debut album, Take Me As I Am, was released in 1993; her first marriage to Dan Hill ended in 1994. Since 1996, Faith has been married to fellow country artist Tim McGraw.
