The First Lady of the United States is the hostess of the White House. The role is usually, but (contrary to popular belief) not always, filled by the wife of the president; bachelor and widowed presidents have had daughters, sisters, nieces or friends as their first ladies. It is unknown what the protocol will be should a woman become president. (See also Presidents of the United States.)
