"Favorite Girl" is a song by Canadian singer Justin Bieber. The song was written and produced by D'Mile, and Antea Birchett, Anesha Birchett, and Delisha Thomas also receive writing credits. Bieber debuted the acoustic version of his song in his official YouTube account after American singer Taylor Swift used Bieber's single "One Time" as background music in one of her video tour diaries. The song was later released exclusively to iTunes as the second promotional single from his debut studio release, My World on November 2, 2009.
The song is mid-tempo and merges teen pop and R&B elements. It debuted at number 12 and 26 in Canada and the United States, respectively. It also charted at number 92 Australia, and at numbers 76 and 27 in the United Kingdom and the UK R&B chart, respectively. Bieber performed the song on several occasions, most of them being the acoustic version of the song, including as a supporting act on Swift's Fearless Tour.
