Gwen Stefani parlayed her breakout stardom as the lead singer of the SoCal ska-punk outfit No Doubt into an enduring career as a pop star. Stefani reached the top of the charts many times during No Doubt's peak. "Spiderwebs," "Just a Girl," and the ballad "Don't Speak" -- all pulled from their 1995 album Tragic Kingdom -- were enduring alternative rock hits. The early-2000s smashes "Hey Baby," "Hella Good," and "Underneath It All" found the group dabbling in pop, dance, and R&B, a musical expansion that coincided with Stefani stepping outside of the band as a featured vocalist on the hits "South Side" by techno superstar Moby and "Let Me Blow Ya Mind" by the rapper Eve. All this extracurricular activity helped set up the launch of Stefani's solo career in 2004 with the album Love.Angel.Music.Baby., a platinum blockbuster that gave her a number one single with the thumping Neptunes collaboration "Hollaback Girl," plus the hits "Cool," "What You Waiting For?," and "Rich Girl," the latter a reunion with Eve. The 2006 record The Sweet Escape consolidated her pop success thanks to the Top Tens "Wind It Up" and "The Sweet Escape," but by that point, Stefani began to venture outside of music. She launched her fashion line L.A.M.B. in 2004, a pursuit she'd develop over the coming decade. She started to dabble in film, an interest that eventually led to her joining the televised singing competition The Voice in 2014. Music remained essential to Stefani's appeal -- she reunited with No Doubt on occasion in addition to returning to her solo career with This Is What the Truth Feels Like, an album released a decade after The Sweet Escape -- yet her position on The Voice underscored how she was a multifaceted star who shone upon every aspect of the entertainment industry.

Born and raised in Fullerton, California, Stefani had a musical epiphany at the age of 17. She had fallen in love with the Madness and Selecter records her brother Eric was constantly spinning. Seeing Fishbone, the Untouchables, and other bands involved in Los Angeles' ska revival scene only reinforced her interest, so she was more than ready when her brother asked her to join a ska band he was forming with a friend named John Spence. Gwen originally shared lead vocals with Spence, but in December of 1987 he committed suicide, leaving the band -- now called No Doubt -- with an uncertain future. According to numerous interviews with the bandmembers after their breakthrough, Gwen was the glue that held No Doubt together during these hard times, pushing the group to keep trying. She was also romantically involved with the band's bass player, Tony Kanal, by this time.

After playing numerous gigs and parties, No Doubt were signed to Interscope in 1991. The label considered their 1992 debut album a flop and refused to financially support a tour or further recordings, but the band refused to give up. The self-financed Beacon Street Collection appeared in 1994 and did well enough to make nice with Interscope, but the band was once again going through a traumatic period behind the scenes. Eric Stefani left to become an animator for The Simpsons and Gwen and Tony's relationship had ended. Gwen wrote a collection of songs focused on heartbreak and rebirth that would become No Doubt's third album, Tragic Kingdom, and the rest, as they say, is history.

With the smash singles "Just a Girl," "Spiderwebs," and "Don't Speak," the album reached the number one spot in Billboard and garnered two Grammy nominations. The press began to focus on Stefani's role in the band. Voted one of People magazine's "50 Most Beautiful People," video and photo shoots focused on her and rumors spread that the other three members of the band were unhappy with the lack of attention they received. This topic of discussion continued as the band released Return of Saturn in 2000 and the heavily reggae-influenced hit album Rock Steady a year later. During this time, Stefani's romantic relationship with Bush frontman Gavin Rossdale became a frequent topic of No Doubt's songs. The pair married on September 14, 2002. She also started doing some work outside the band, lending her vocals to the remix of Moby's "Southside" and rapper Eve's "Let Me Blow Your Mind."

After Rock Steady, No Doubt took a break. Stefani approached Kanal about producing an off-the-cuff solo project that would be influenced by her non-ska favorites. Prince, the Time, Club Nouveau, and Madonna were the names thrown around and the idea was to make the project "fast and easy." Over time, the "fast and easy" record morphed into something much bigger. Old friend, former labelmate, and hit songwriter Linda Perry became involved and the project became much more polished, slick, and dance-oriented. A pile of high-profile collaborators -- Dr. Dre, the Neptunes, Dallas Austin, Andre 3000, Nellee Hooper, Jimmy Jam, and Terry Lewis -- became involved. In September of 2004, the infectious and hyper dance single "What You Waiting For?" appeared with its accompanying video dominating MTV.

The album, Love.Angel.Music.Baby., hit the shelves in November with surreal artwork that introduced Stefani's four-woman "posse," the Harajuku Girls. The all-Asian Harajuku Girls were inspired by Stefani's fascination with the Harajuku girls of Japan, young club kids with a flippant and fun attitude toward fashion. Appearing with Stefani live, in videos, and in photos, the Girls quickly drew criticism from the Asian community, angry about the rumor that they had to sign a contract to never speak English even though they could, and that Stefani's Girls looked nothing like the "real" Harajuku girls. Nonetheless, the album was a hit and continued to roll out singles. Based on a dancehall cover of Fiddler on the Roof's "If I Were a Rich Man," "Rich Girl" became the next smash, reuniting Stefani with Eve. The cheerleader kiss-off anthem "Hollaback Girl" was the third success. While the singles were dominating pop and dance radio, Stefani appeared as Jean Harlow in Martin Scorsese's The Aviator. With music and movies checked off, Stefani moved into the world of fashion and introduced her clothing line, L.A.M.B. Taking her influence to the world of tech, she designed the Harajuku Lovers' 4.1 MP Digital Camera for Hewlett-Packard. The camera was released in a limited edition with a Stefani-designed case and a biographical DVD.

Late in 2005, Stefani discovered she was pregnant with her first child, but her schedule remained busy in 2006: along with working on L.A.M.B., she released a line of limited-edition fashion dolls complete with outfits from her videos and tours, and worked on her second solo album with producers including Akon, Swizz Beatz, Tim Rice-Oxley of Keane, Nellee Hooper, the Neptunes, and Tony Kanal. That spring, Stefani gave birth to a boy. The Neptunes-produced, Sound of Music-sampling "Wind It Up" arrived later that fall and heralded the full-length The Sweet Escape, which was released on the same day as the live DVD Harajuku Lovers Live.

No Doubt announced a return to the studio in 2008, but progress slowed to a crawl as the band experienced a bout of writer's block and the Rossdale-Stefani family continued to grow with their second child, Zuma Nesta Rock. The band maintained their momentum by touring through 2009. No Doubt eventually released Push and Shove in 2012, featuring a mix of Rock Steady-esque dancehall bangers and new wave ballads similar to Stefani's solo material. In February 2014, Stefani and Rossdale had their third boy, Apollo Bowie Flynn. Later that year, Stefani joined the judges panel on The Voice with her friend Pharrell, opening the pair to a number of subsequent collaborations. Stefani lent her vocals to fellow Voice coach Adam Levine for Maroon 5's "My Heart Is Open." She also appeared on tracks with Calvin Harris and Snoop Dogg.

By late 2014, Stefani was in the midst of a full-scale comeback, releasing a pair of singles: the Ryan Tedder/Benny Blanco-penned "Baby Don't Lie" and another Pharrell production, "Spark the Fire." The following year, she contributed the song "Shine" to the Paddington Bear movie soundtrack and a duet with Eminem on "Kings Never Die" from Southpaw. In August 2015, Stefani and Rossdale filed for divorce. A third song -- "Used to Love You" -- was released months later. It gained moderate airplay and was the only comeback single to be included on her third project, This Is What the Truth Feels Like, which was released in March 2016 and debuted at number one on the Billboard 200. The second official single from the album, "Make Me Like You," was accompanied by a video that Stefani recorded live during the 2016 Grammy Awards. Later that year, she provided the voice for the DJ Suki character in the animated movie Trolls and, along with Justin Timberlake, appeared on several songs from the film's soundtrack.

In September 2017, she released the seasonal album You Make It Feel Like Christmas, which featured a duet with her Voice co-star -- and current romantic partner -- Blake Shelton. Stefani duetted with Shelton on his 2020 single "Nobody But You," a song featured on the compilation Fully Loaded: God's Country, and added "Here This Christmas" to a reissue of You Make It Feel Like Christmas. At the end of the year, she returned to pop music with "Let Me Reintroduce Myself," a single that built upon the effervescent sounds of No Doubt. ~ David Jeffries & Neil Z. Yeung, Rovi
