Halliwell was born in Watford, Hertfordshire England U.K to Laurence Francis Halliwell (1922-1993), who was of English/Swedish descent, and his wife Ana María (née Hidalgo), who was of Spanish descent from Huesca, Spain. She grew up on on a council estate in North Watford, Hertfordshire. For a brief time, Halliwell's mother tried to bring her up as a Jehovah's Witness.

Before starting her music career, Halliwell had worked as a nightclub dancer in Majorca, a model and presenter on the Turkish version of Let's Make a Deal and as a glamour model. Following her rise to fame with the Spice Girls, nude photos of Halliwell were re-published in a number of top-shelf magazines in the UK, as well as in Playboy and Penthouse.

Geri first found fame as one of the five members of the girl group the Spice Girls, and was dubbed originally Sexy Spice because of her red hair and attitude but changed it to Ginger Spice in order to appeal better to younger fans.
