Gwen Renée Stefani (/ˈɡwɛn stɛˈfɑːni/; born October 3, 1969) is an American singer, songwriter, fashion designer, and occasional actress. Stefani fronts the rock/ska punk band No Doubt, whose 1995 album Tragic Kingdom propelled them to stardom, selling 16 million copies worldwide. It spawned the singles "Just a Girl", "Spiderwebs", and "Don't Speak". The band's popularity went into decline with its fourth album, Return of Saturn (2000), but Rock Steady (2001) introduced reggae production into its music, and generally received positive reviews.
Stefani recorded her first solo album Love. Angel. Music. Baby. in 2004. The album was primarily inspired by music of the 1980s, taking Stefani's work further into more pop and dance music, and enjoyed international success with sales of over seven million. The album's third single "Hollaback Girl" became the first U.S. digital download to sell one million copies. Stefani's second solo album The Sweet Escape (2006) yielded "Wind It Up", a moderate worldwide success, and "The Sweet Escape". She won the World's Best-Selling New Female Artist at the World Music Awards 2005.
