Geraldine Estelle Halliwell-Horner (née Halliwell; born 6 August 1972) is an English singer, television personality, author, and actress. She rose to fame in the mid-1990s as a member of the pop group the Spice Girls, in which she was nicknamed Ginger Spice. With over 100 million records sold worldwide, the Spice Girls are the best-selling female group of all time. Their slogan "girl power" was most closely associated with Halliwell and her Union Jack dress from the 1997 Brit Awards also became an enduring symbol. Halliwell left the Spice Girls in 1998 and launched a solo career with the album Schizophonic (1999), which produced the UK number-one singles "Mi Chico Latino", "Lift Me Up" and "Bag It Up"; the lead single, "Look at Me", reached number two. Her second album, Scream If You Wanna Go Faster (2001), was preceded by the chart-topping lead single, "It's Raining Men" and earned her a Brit Award nomination. Her third album, Passion (2005), produced the UK top five single "Ride It". Halliwell has reunited with the Spice Girls on several occasions, including a greatest hits album (2007) and two concert tours: the Return of the Spice Girls (2007–2008) and Spice World (2019). Alongside her music career, Halliwell has served as a judge on television talent shows, including Popstars: The Rivals (2002), The X Factor UK (2010, 2012), and Australia's Got Talent (2013). She has appeared in the films Spice World (1997), Crank: High Voltage (2009) and Gran Turismo (2023). As an author, she has released two autobiographies: If Only (1999) and Just for the Record (2002); the children's book series Ugenia Lavender (2008), and the young adult novel series Rosie Frost (2023–present). Halliwell is a Goodwill Ambassador for the United Nations Population Fund (UNFPA).
