[6] "A Little Bit" was used to promote Bally Total Fitness and thus, a limited CD single pressing was made available to people who joined the club.

[11] Simpson adopts breathy vocals for the song,[12] and the lyrics talk about what she expects from her partner: "A little more time, a little less wait / A little more heart, a little less break".

Kirsten Koba of PopMatters gave a positive review, writing "with pop star sass, she belts out [...] proving that she's a girl with attitude — and fierce rhyming ability.

[15] Chuck Taylor of Billboard praised the song's production, writing that it "locks [this one] inside the head long after it's faded from the speakers.

"[2] Larry Printz of The Morning Call also gave a favorable review, writing that the song "benefit[s]" from the start-and-stop hooks.

[11] Yushaimi Yahya of The Malay Mail, who was critical of the album as a whole, pointed out that Simpson sounded "decent" on the track.

[16] However, Chuck Campbell of Daily News noted Simpson's singing as "breathless whispers" and deemed the song as being "heavily processed.

"[12] The song debuted at number sixty-two on the Australian Singles Chart, on the week dated November 5, 2001, which became its peak position.

Later, Simpson dances beside a male dancer while wearing sunglasses and a white top with a bedazzled American flag.

In the video's final scene, Simpson, accompanied by the same dancers from the beginning, perform choreography in a red room, and dance with futuristic pole-stands.

[25] The same month, she sang the song on the 2001 Dick Clark's New Year's Rockin' Eve, along with "Irresistible",[26] and on the Hot 107.9 Mistletoe Meltdown.

[27] Mark Bialczak of The Post-Standard wrote that Simpson "sure sounded like a diva – especially with the bulked-up tape track that accompanied her singing.

"A Little Bit" was recorded by English singer and Pop Idol runner-up Rosie Ribbons, for her debut studio album Misbehaving.

It reached number nineteen on the UK Singles Chart, and was also accompanied by a music video, which showed Ribbons dancing with her backup dancers.

Ribbons' version of "A Little Bit" was released as the second single from her debut album titled Misbehaving, on January 13, 2003, through Telstar Records.

[34] The reviewer added "[so] often we are bombarded with wannabes with weak vocals and insipid songs, [Rosie] shows us that there is life after pop idol and with 'a little bit' of cred.

[40] Similarly, Julie MacCaskill of the Daily Record dismissed it as "a lacklustre affair with the wannabe star ditching her Mariah sound- a-like singing in favour of becoming a Kylie clone".

[44] A promotional music video for the song was filmed, which showed Ribbons wearing heavy makeup and donning a stylish costume.
