"I Will Be" is a song co-written and originally performed by Franco-Canadian singer Avril Lavigne, which was included on the North American, Taiwanese, and Japanese limited editions of her third studio album The Best Damn Thing and as an iTunes Store pre-order bonus track in 2007; British singer-songwriter Leona Lewis covered the song for her debut studio album, Spirit, also released in 2007. Max Martin and Lukasz Gottwald also co-wrote the song, whilst production was helmed by Gottwald under his production name Dr. Luke. It was co-produced by Steven Wolf and Max Beckley and Smit. It is a piano and guitar led song. It garnered a mixed response from music critics, with some critics praising Lewis's vocal performance and delivery, whilst others described it as emotionless.
Upon the release of Spirit in November 2007, the song peaked at number 160 on the UK Singles Chart due to strong digital download sales. It was released for US Contemporary hit radio airplay on 6 January 2009. Throughout January to March 2009, it also made an impact on the Canadian and United States charts; in the former it peaked at number 83, while it peaked at number 66 on the Billboard Hot 100 in the latter. However, it was more successful on the US Adult Pop Songs and Pop Songs charts, peaking at numbers 23 and 24, respectively. As part of promotion, a music video was shot in New York City and featured Chace Crawford as Lewis's love interest. In January 2009, she performed the song on the Late Show with David Letterman.
