First Lady or First Gentleman is an unofficial title usually used for the spouse, and occasionally used for the offspring or other relative, of a non-monarchical head of state or chief executive. The term is also used to describe a person seen to be at the top of her profession or art. The title has also been used for the spouse of a head of government who is not also head of state. It has also been used to refer to the spouses of the leaders of administrative divisions within a country. The title is often used for the wives of Christian pastors in denominations where married clergy are the norm. Source: Wikipedia (en)
