Three singles were released from the album. The lead single, "So Yesterday", was released in July 2003 to mixed reviews. The song failed to make much of an impact in the United States, peaking in the top 50. Internationally, it peaked within the top-ten of the music charts in Australia, Canada, France and the United Kingdom. The second single, "Come Clean", released in early 2004, was more successful in the United States, peaking at number 35 on the US "Billboard" Hot 100 and becoming her best-selling single in the country. The third and final single from the album, "Little Voice", was only released in Australia. Duff further promoted the album with the "Metamorphosis Tour", which began in November and ended in December 2003.
