Gwen Renée Stefani (/stəˈfɑːni/; born October 3, 1969) is an American singer, songwriter, fashion designer, and actress. She is the co-founder and lead vocalist of the ska band No Doubt. During the band's hiatus, Stefani embarked on a solo career in 2004 by releasing her debut studio album Love. Angel. Music. Baby. Inspired by pop music of the 1980s, the album was met with both critical and commercial success. It spawned three major worldwide hit singles: "What You Waiting For?," "Rich Girl," and "Hollaback Girl," the latter becoming the first US digital download to sell one million copies. In 2006 Stefani released her second studio album The Sweet Escape. The album produced two successful singles: "Wind It Up" and the album's title track "The Sweet Escape." Including her work with No Doubt, Stefani has sold more than 30 million albums worldwide.

As a solo artist, Stefani has won several music awards, including a Grammy Award, a World Music Award, an American Music Award, a Brit Award, and two Billboard Music Awards. In 2003, she debuted her clothing line L.A.M.B. and expanded her collection with the 2005 Harajuku Lovers line, drawing inspiration from Japanese culture and fashion. Stefani performs and makes public appearances with four back-up dancers known as the Harajuku Girls. She was married to British musician Gavin Rossdale from 2002 to 2015 and they have three sons. Billboard magazine ranked Stefani the 54th most successful artist and 37th most successful Hot 100 artist of the 2000–09 decade.VH1 ranked her 13th on their "100 Greatest Women in Music" list in 2012.

"Yummy" is a song by American singer and songwriter Gwen Stefani, featuring American musician Pharrell Williams, from her second solo studio album, The Sweet Escape (2006). The song was written by Stefani and Williams and produced by the latter. It was recorded during several sessions in Miami, Florida, in July 2005, for an intended EP or as extra tracks on a DVD. The songs also ended up being playing during a premiere fashion show for Stefani's fashion line, L.A.M.B..

Interscope Records released the track as a promotional single a month before the album's release in November 2006. It was released as a three-track maxi promo single and as a 12" vinyl single, where both of them featured a radio edit, an instrumental, and a cappella version of the song.

Though the song was released before the release of her studio album, The Sweet Escape, it was a commercial failure and it did not chart in the United States.

Background and recording

After the release of Love. Angel. Music. Baby., Stefani originally intended to return to No Doubt and start recording tracks for their sixth studio album, which would later be titled: Push and Shove, but instead Pharrell Williams convinced her to record several more songs in Miami, Florida, in July 2005. Together they recorded "Wind It Up", "Orange County Girl", "U Started It", "Breakin' Up", "Candyland", and "Yummy". Although, the songs were primarily recorded for its original intended purposes, "Wind It Up" and "Orange County Girl" were included in Stefani's 2004 concert tour, Harajuku Lovers Tour.
