A remix featuring Damian Marley was produced for the song's release as the album's fourth single on August 26, 2007, by Interscope Records.

The song's music video was directed by The Saline Project and was shot in Puerto Rico and Jamaica, featuring Stefani and the Harajuku Girls.

[1] In September 2006, during the Fashion Week, MTV News interviewed Swizz Beatz and he said to be working with Stefani as well, claiming: "She's always taking it to the next level.

The single version of the song features a "loping hip-hop beat and a staccato piano sample" while Stefani "splits wailing time with a chorus of alarms," according to Mark Pytlik of Pitchfork Media.

[13] Norman Mayers of Prefix Magazine praised Swizz Beatz for "coming up with the most likely heir to the Hollaback crown, with the bumping chants and boasting raps".

[14] However, Alex Miller of the NME characterized it as "a track so desperate to be a club banger, its fraying tapestry of hand-claps, sirens and triumphalism has all the grace of a Pepsi Max advert".

"[16] John Murphy of musicOMH gave the single a mixed review, writing "when the self-consciously wacky and kitsch side to her personality surfaces, as on the inane 'Now That You Got It', the temptation is to dive for the 'off' switch".

Fraser McAlpine of the BBC Chart Blog conveyed it as a "perfect case" of Stefani making songs which are sleek and tough on the outside, but have a middle which is pure and vulnerable, ultimately rating it four out of five stars.

[11] Similarly, CBBC's Newsround portrayed the sound as "a very laid back, summery tune" which, it claims, will still have its readers "humming it next week".

Nevertheless, in the United States, it was commercially unsuccessful, not entering any of the US Billboard charts, making it Stefani's first song as a solo artist to not do so.

Internationally, it reached the top-twenty in a few European countries, having its higher chart position in Norway, where it debuted and peaked at number seventeen.

[23] The Puerto Rico scenes were shot a day after Stefani's concert in the city, as part of The Sweet Escape Tour, on July 19, 2007.

Many parts of the video were shot in a studio, including scenes of Stefani riding a motorcycle in front of a green screen.

As the chorus begins and Stefani, the Harajuku Girls and Marley are playing board games under a shelter near the lake side.
