It was written by Fergie and will.i.am, the latter also produced the track, while Bobby Troup receives a songwriting credit due to its sample.

The song's lyrics about being clumsy and in love flow alongside its computerized and bleeping beat taken from "The Bubble Bunch" by Jimmy Spicer, as well as a sample of "The Girl Can't Help It", originally performed by Little Richard.

"Clumsy" peaked at number five on the US Billboard Hot 100 chart, becoming Fergie's fifth straight top ten hit in the US.

The song's music video, directed by Marc Webb and Rich Lee, is stylized like a pop-up book and features Swedish model Alex Lundqvist as Fergie's love interest.

[1] will.i.am said, "'Clumsy' was recorded in the John Lennon bus [a traveling music education lab], like in a parking lot in Pittsburgh right next to Shakey's.

[8] Daniel Wolfe of About.com commented, "The songstress is “slippin’ and stumblin’” all over a laid-back beat and Casio keyboard lines.

"[6] The electronic beeps of the melody are sampled from 1982's "The Bubble Bunch" by early hip-hop artist Jimmy Spicer.

During the song's middle eight, she is singing in a pop-up space shuttle and at the same time at the concert, she knocks down a dancer and the stage begins to collapse.

To conclude the video, Fergie is getting ready on a rooftop photo shoot and she sits down on a ledge to read a text message, and she falls off the building and the man catches her.

[14] Tamar Anitai of MTV Buzzworthy wrote that the video "is basically an amalgam of many things we find hard to resist: Amy Winehouse-style retro-nuevo beehives, free falling, fake planes, cheesy acting, En Vogue-era little black dresses, old-school video games and um, hot dudes, including one who, unsurprisingly, looks like Josh Duhamel."

As much as we love MAC and DSquared, it's hard to miss those blatant shout outs, as well as the fairly gratuitous Motorola plug.

He called the song "a good bit of breezy pop fun", but wrote that it "may not be as immediately engaging as her previous hits" and that "there is nothing striking or even slightly epic about the tune."

However, he praised the sample of "The Girl Can't Help It", Fergie's "melodious, breathy vocal runs", and the song's goofy lyrics on love.

[28] "Clumsy" is Fergie's fourth most downloaded song, behind "Big Girls Don't Cry", "Fergalicious" and "Glamorous", and ahead of her first single, "London Bridge".

[34] Fergie performed "Clumsy" alongside her previous single "Big Girls Don't Cry" in the 2007 American Music Awards on November 18, 2007.

[35] She also performed the song on NBC's The Today Show alongside "Big Girls Don't Cry" and "Barracuda" with part of "Welcome to the Jungle" on May 20, 2008.
