Geraldine Estelle "Geri" Halliwell (born 6 August 1972) is a British pop singer-songwriter, clothes designer, author and actress. Halliwell came to international prominence in the late 1990s as Ginger Spice, a member of girl group the Spice Girls. She reportedly amassed a $30 million fortune during her last two years in the group. Halliwell launched her solo career in 1998, releasing her album Schizophonic. She has since released two more studio albums - Scream If You Wanna Go Faster and Passion - as well as four singles that reached number one on the UK Singles Chart: "Mi Chico Latino", "Lift Me Up", "Bag It Up" and "It's Raining Men".

In 2008 Halliwell published a book series named Ugenia Lavender. As a solo artist, Halliwell has sold 12 million records worldwide, and been nominated for four Brit Awards (in 2000 and 2002).

In 1999 she wrote her first autobiography If Only, in which she described her life as a Spice Girl. Her second autobiography was released in 2002.

She is expected to release her fourth studio album in late 2012.
