It also became Fergie's third best-selling song in the United States, earning a double platinum certification from the Recording Industry Association of America (RIAA).
An accompanying music video directed by Dave Meyers features Fergie, her fellow members of the Black Eyed Peas, and Ludacris.
"Glamorous" experienced a resurgence in 2022, when rapper Jack Harlow sampled the song for his single "First Class", which also topped the Billboard Hot 100, amongst other charts.
The technical work performed on "Glamorous" includes engineering, which was orchestrated principally by Travis Daniels and was assisted by Mack Woodward.
Tal Herzberg, who has worked the Black Eyed Peas on previous studio recordings, performed additional engineering on the track with the use of Pro Tools.
Tony Maserati was signed as the principal mix engineer while Ryan Kennedy assisted him at The Record Plant in Hollywood, California.
Directed by Dave Meyers, and shot in an anamorphic 1.85:1 widescreen aspect ratio, the video, which had its world premiere on MTV's TRL on February 7, 2007, begins in the year 1994 with Fergie and Polow da Don at a keg party in East Los Angeles before she was famous, with everyone at the party shouting "If you ain't got no money take yo broke ass home".
The camera then rotates upward where it is present day and Fergie is lounging in a Gulfstream G550 business jet, and as the chorus suggests, "flying first class, up in the sky".
The video then returns to present day where Fergie and Ludacris are shown shooting a film called Glamorous, a throwback to Bonnie and Clyde.
Fergie is then shown at the same kegger from earlier in the video, with her Black Eyed Peas bandmate apl.de.ap, Alfonso Ribeiro, Polow da Don, and B-Real from Cypress Hill with whom she clinks plastic glasses, followed with the plane she is on in the present day flying into London as the sun sets.
Bill Lamb of About.com gave "Glamorous" a three and a half star rating, praising the song's smooth R&B feel but dismissed its use of spelling out the title in the lyrics.
Lamb also noted that "The frequent sparks of self-referential humor present in much of Fergie's music are missing here which limits the distinctiveness of this song" and explained it "veers a bit uncomfortably close" to Gwen Stefani's 2005 single "Luxurious" (Love.
He concluded his review, writing "unlikely to be a 3rd #1 for Fergie, and it may even struggle for top 10 status, but it is likely to linger as pleasant pop filler on the radio for the first few months of 2007.
1 for a quarter when there ain’t shit else going on" and called Fergie's mid-song interjection of "fuck y'all" more convincing than the profanities present in RJD2's The Third Hand (2007), naming it the best gratuitous curse word in the top ten.
[12] In the United States, "Glamorous" made its debut on the Billboard Hot 100 at number 98 on the issue dated January 27, 2007, while the previous single "Fergalicious" was still inside the top five.
The single went on to sell 3,012,000 digital downloads in the United States, enough to earn a double-platinum certification by the Recording Industry Association of America (RIAA).
