Caillat was born in Malibu, California, and grew up in Newbury Park, California. Her father, Ken Caillat, co-produced Fleetwood Mac's Rumours (1977) and Tusk (1979) albums. When she was an infant, her parents gave her the nickname "Coco", which she would later name her debut album. Caillat took piano lessons as a child, but lacked significant inspiration until she turned 11 years old, when she became enthralled with Lauryn Hill's performance in Sister Act 2. She realized that she wanted to be a singer, and began taking vocal lessons, performing onstage for the first time in sixth grade. Since then she has covered the Roberta Flack song, "Killing Me Softly", which had previously been covered by Lauryn Hill, and Hill's own "Tell Him".
