Ferguson was born in Hacienda Heights, California, the daughter of devout Roman Catholic school teachers Theresa Ann (née Gore) and Jon Patrick Ferguson. Her ancestry includes English, Irish, Mexican, Native American, and Scottish. She was raised Roman Catholic and attended Mesa Robles Middle School and Glen A. Wilson High School. She was a cheerleader, straight-A student, spelling bee champion, and Girl Scout.
Ferguson studied dance and began to do voiceover work; she provided the voice for Sally in two made-for-television Peanuts cartoons, It's Flashbeagle, Charlie Brown (1984) and Snoopy's Getting Married, Charlie Brown (1985), as well as on four episodes of The Charlie Brown and Snoopy Show. From 1984 to 1989, she starred on the TV show Kids Incorporated and was the longest running cast member; she starred in the first six of the show's nine seasons. Ferguson was a member of the female trio Wild Orchid, which she fronted with Stefanie Ridel and fellow Kids Incorporated star Renee Sandstrom. By 1992, the girls began meeting with record labels, but they still could not get a recording contract. They eventually signed a music publishing deal with Sony Publishing before signing a record contract with RCA Records in 1994. In April 2007, she gave an interview in which she admitted that she went on a sex and drugs spree when she turned eighteen, saying: "I have had lesbian experiences in the past. I won't say how many men I've had sex with—but I am a very sexual person."
Wild Orchid's first single, "At Night I Pray", debuted on the Billboard charts in September 1996. In March 1997, the band released their self-titled debut album, which debuted at number one. In September 1998, they released their second album, Oxygen, which was a commercial failure, only selling 200,000 copies worldwide. From June 16 to August 28, 1999, they opened for Cher's Do You Believe? Tour alongside Cyndi Lauper, which took them to 52 cities across the United States and Canada. They completed a third album, which their record label declined to release, and Ferguson left the group in September 2001. In 2006, Ferguson told Entertainment Weekly that both frustrations with the band's image and personal drug problems led her to leave Wild Orchid.
The Black Eyed Peas were recording their third album, Elephunk (2003), when will.i.am invited Ferguson to try out for a song called "Shut Up". She got the gig and instantly bonded with the trio, going on to record five additional songs on the album. The following spring, shortly before Elephunk came out, Interscope chairman Jimmy Iovine offered Ferguson a permanent spot to take over vocal duties and fill the void left by background singer Kim Hill's departure in 2000. In a positive review of The Black Eyed Peas' new-found style, Rolling Stone noted that since 2002, when the group "hired a blond bombshell named Stacy 'Fergie' Ferguson and gave up their pursuit of backpack-rapper cred, they have made a kind of spiritual practice of recording futuristic songs – a total aesthetic commitment that extends from their garish wardrobes to their United Colors of Benetton worldview." From Elephunk came "Where is the Love?", which became The Black Eyed Peas' first major hit: it peaked at number eight on the Billboard Hot 100 and topped the charts in several other countries. The album subsequently spawned "Shut Up", which topped the charts in many markets. The third single from the album, "Hey Mama", reached the top 10 in several European countries and later peaked at number twenty-three in the United States. In 2004.
Their next album, Monkey Business, was released on June 7, 2005 and debuted at number two on the U.S. Billboard 200 albums chart, selling over 295,000 copies in its first week and was later certified triple platinum by the RIAA. Their next and last commercially released single from the album was "Pump It", which borrows much of its sound from "Misirlou", specifically Dick Dale's version; it peaked at number 8 in Australia but 18 in America. The album's first single, "Don't Phunk with My Heart", was a hit in the United States, reaching number three on the U.S. Hot 100 and earned them another Grammy for Best Rap Performance by a Duo or Group. "Don't Lie", the second single from the album, saw success on the U.S. Hot 100, reaching No. 14, although becoming somewhat more successful in the UK and Australia, reaching a peak of No.6 in both countries. "My Humps", another song from the album, immediately achieved commercial success in the U.S. and fairly substantial radio play despite the sexually suggestive lyrics, reaching number three on the U.S. Hot 100 and number one in Australia, making it their fourth Australian number one single. However, many mocked the song for its poor lyrical content; John Bush, writing for AllMusic, described it as "one of the most embarrassing rap performances of the new millennium". In autumn 2005, The Black Eyed Peas toured with Gwen Stefani, as supporting act. In December 2005, they embarked on the "European Tour". In March 2006, The Black Eyed Peas toured again, as the featured headliner for the Honda Civic Tour.
Ferguson's debut solo album, The Dutchess, was released in September 2006. It was initially recorded in 2005. The songs on the album are "from a seven-year period, but [Interscope CEO] Jimmy Iovine heard some [tracks] and was like, 'This is great, let's put it out'. One of the album's executive producers and fellow Black Eyed Peas member will.i.am stated that she was "writing about her personal struggles and casting her demons away and feminine power. [It's] her singing for young girls to be strong, and what they’re going through in life, just growing up in this world of uncertainty." "London Bridge" was released as the album's lead single on July 18, 2006 to radio stations and on August 7, 2006 on the iTunes Store. The urban pop track caused controversy due to its double entendre title, but became a huge success, topping the Billboard Hot 100 (for three weeks) and New Zealand charts, while also reaching the top-ten in over twelve countries. The music video for the song features The Black Eyed Peas members as well as Fergie on the Tower Bridge, among other scenes.
The following single, "Fergalicious", was released on October 23, 2006. The track, which features will.i.am, managed to reach number two on the Billboard Hot 100, the top-five in Australia and New Zealand, although it peaked lower than "London Bridge" in Europe. Its music video features Fergie as Willy Wonka in a candy factory. "Glamorous" was released as the third single from the album, on February 20, 2007. The track, which features Ludacris, became another number-one single for Fergie in the United States, and also reached the top-ten in over seven countries. The fourth single, "Big Girls Don't Cry", was released on May 22, 2007. The ballad became a huge success worldwide, topping the charts of ten countries, including Australia, Canada and the United States; it was also the album's most successful single in Europe.
