Power couples have always been a big part of the country music scene. From classic pairings such as George Jones and Tammy Wynette to more recent unions, country couples are a source of entertainment and inspiration -- and, often, speculation -- for country music fans.

Today's country power couples run the gamut. Fellow superstars Tim McGraw and Faith Hill have merged their professional and personal lives, performing together on record and onstage; though Amy Grant is more of a contemporary Christian singer, her union with country superstar Vince Gill has made them one of the most influential couples in Nashville; and Keith Urban's marriage to actress Nicole Kidman has brought Nashville -- and country music -- some added star power.
