Millie (born Millicent Dolly May Small, 6 October 1942, in Clarendon, Jamaica) — often known as "Little Millie Small" — is best known as the singer of the 1964 hit, "My Boy Lollipop".

In Northern Ireland, the term millie came to be used in the 19th Century to refer to mill-workers - usually young, working class women who worked in factories within Ireland's huge linen industry. In more recent times, it has become a derogatory term for working class, harsh-spoken women. Often, these women are young, unemployed mothers on benefits.
