2009–2012: Continued success with the Black Eyed Peas
In early 2009, Fergie and the group left A&M Records; both remained with Interscope Records. The group's fifth studio album, The E.N.D ("The Energy Never Dies"), was released on June 9, 2009. The overall sound of the album has a more electro hop beat rather than the usual hip pop/R&B feeling of their previous albums. In its first week, the album sold 304,000 copies and debuted at number 1 on the Billboard 200. They released "Boom Boom Pow" as the lead single from The E.N.D. in March 2009. It reached number one on the US charts and became the group's first chart topper. As of March 2011, the album has sold over 3,000,000 copies in the US alone. In France, the album spent 55 weeks inside of the top 10 with 11 at No. 1. They subsequently released a second single from the album, "I Gotta Feeling", which proved an even greater success than the first: it moved from number two behind "Boom Boom Pow" to the top spot in July, and stayed for 14 straight weeks at number one on the Billboard Hot 100, the longest stay at the top of 2009. The two hit singles back to back kept the Black Eyed Peas on the top for 26 consecutive weeks, from April 18 through October 16. Fergie bought a stake in the professional football team the Miami Dolphins in 2009, and has performed at the team's football games numerous times.
"Meet Me Halfway" was released as the third single from the album in September 2009. The single reached number one in the UK and Australia. It also peaked at seven on the Billboard Hot 100. In October 2009, Fergie became a part owner of the Miami Dolphins. "Imma Be" was released as the fourth single; it reached number one on the Billboard Hot 100 for two weeks.
