Geraldine Estelle “Geri” Halliwell (born 6 August 1972) is an English pop singer-songwriter, clothes designer, author and actress. Halliwell came to international prominence in the 1990s as Ginger Spice, a member of girl group the Spice Girls. On 30 May 1998, Halliwell left the Spice Girls due to depression and differences within the group. In 2007, it was announced that the Spice Girls had reunited, and that Halliwell had rejoined the group. Together they embarked on the Return of the Spice Girls tour and released a Greatest Hits album. Halliwell has reportedly amassed a $30 million fortune during her last two years in the group.

In 1999, Halliwell launched her solo career and released her debut album, Schizophonic, which spawned three number ones at the UK Singles Chart: “Mi Chico Latino,” “Lift Me Up,” and “Bag It Up,” while the lead single, “Look at Me,” peaked at number 2. In 2001, Halliwell followed up with her second album, Scream If You Wanna Go Faster; the first single, “It’s Raining Men,” was a major hit worldwide, it peaked at number 1 in the UK and peaked in the top 10 in over 27 countries, becoming Halliwell’s biggest hit to date. Halliwell released her third studio album, Passion, in 2005. Geri has been nominated for four Brit Awards (in 2000 and 2002). After a few years of relative obscurity, in April 2010, Halliwell announced that she had started working on new music. In April 2013, the Nine Network announced that she would become the fourth judge on Australia’s Got Talent. On 12 September 2013, it was announced that Halliwell would return to the music industry in Australia with the release of her first solo single in nearly eight years, “Half of Me”. With 11 number one singles (7 as part of The Spice Girls, 4 as a solo artist) she is the female singer with the third most number one singles in UK chart history.
