Coco is the debut album by Colbie Caillat. The album was released on July 17, 2007 in the United States, debuting at #5 on the Billboard 200 and selling 51,000 copies in the first week. The album was certified 2x Platinum by the RIAA with shipments to U.S. retailers of 2,000,000 units. The album's first single, a smash hit, was "Bubbly", followed by a second single, "Realize", and the third, "The Little Things", which became the final single from the album in the United States. According to one of the pictures on Caillat's MySpace page, it was assumed that her song "Battle" would have been the fourth and final single from Coco. Because of her collaboration with Jason Mraz, "Lucky", being released as a single and with the release of her second album, it is assumed that the single and music video were canceled and all promotion was then focused on "Lucky" and her second album Breakthrough. It also became Caillat's best-selling album, to date, selling 2,100,000 copies in the United States and over 3,000,000 copies around the world. Caillat supported the album with the Coco World Tour.
Critical reviews of the album were mixed. Allmusic said "she sings about simple, everyday things in an unassuming manner, letting her melodies and girl-next-door charm carry the day". Chuck Arnold (of People magazine) said that "although the midtempo tracks start to blend together, this California girl keeps the sun-kissed sounds coming." Caryn Ganz (with Rolling Stone) said Caillat has "soulful swing, but over a dozen bland, sunny tunes, it's hard to pin her down."
