Stacey Ferguson

The Black Eyed Peas were recording their third album, 2003's Elephunk, 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.
From Elephunk came "Where is the Love?", which became The Black Eyed Peas' first major hit, peaking at number eight on the Billboard Hot 100, but topping 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" hit top 10 in many European countries and later reached number twenty-three in the US. In 2004, The Black Eyed Peas embarked on the worldwide Elephunk Tour.
Their next album, Monkey Business, was released in June 2005. Monkey Business debuted at number two on the Billboard 200. The album's first single, "Don't Phunk with My Heart", reached number three in the US and earned them a Grammy for Best Rap Performance by a Duo or Group. "Don't Lie", the second single from the album, saw success on the Billboard Hot 100, reaching number fourteen. "My Humps", another song from the album, immediately achieved commercial success in the US, reaching number three on the Hot 100 and number one in Australia. In autumn 2005, The Black Eyed Peas set off to tour with Gwen Stefani, as supporting act. In December 2005, they embarked on the "European Tour". In March 2006, The Black Eyed Peas hit the road again as the featured headliner for the Honda Civic Tour.
