It borrows melodic and lyrical passages from "Be My Baby" by The Ronettes. The chorus to Buena's version is sung by British soul singer Amy Winehouse. The single was a commercial failure for Mutya and her label, charting at #73 on the UK Top 75. However, promotion for the single managed to get the album back into the UK Albums Chart, debuting at #88 and peaking at #83. "B Boy Baby" has since been used in various adverts on UK television. In 2008, the song surged in downloads and peaked at #1 on the Greek's iTunes Top 10 Singles Chart.
The video premiered on 4Music on December 4, 2007. It was filmed in Millennium Square, Bristol, and features "The Physical Jerks" - a group of break dancers. Amy Winehouse was supposed to be featured in the video, however due to her personal issues going on at the time she failed to appear.
