Gwen Renée Stefani (pronounced /??w?n st??f??ni/; born October 3, 1969) is an American singer and fashion designer. Stefani serves as lead vocalist for the rock band No Doubt. With previous material ranging from punk rock to new wave music, their third wave ska oriented third studio album Tragic Kingdom (1995) 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) focused on dancehall production traits, and generally received positive reviews.
