Geri Halliwell was an original member of the 1990's pop group The Spice Girls. Her nickname was Ginger Spice, though she was also called Sexy Spice. The all-female quintet was a worldwide sensation late in the decade, with songs like the chart-topping "Wannabe" and a 1997 movie, SpiceWorld. Halliwell left the group abruptly in May of 1998 and began a successful solo singing career. (Halliwell was the first to leave the Spice Girls, though others did the same and the group went into permanent hiatus.) Her 1999 album Schizophonic included the hit singles "Look at Me" and "Lift Me Up." Her other albums include Scream If You Wanna Go Faster (2001) and Passion (2005). She has written two memoirs: If Only (2000) and Geri: Just for the Record (2003). Halliwell's first child, a daughter named Bluebell Madonna, was born on 14 May 2006. Halliwell did not identify the father. She told reporters that the first name was inspired by the "precious flower," and that the middle name was in honor of the singer Madonna. Halliwell was named a Goodwill Ambassador for the United Nations in 1998.
