Forsberg was born on 2 May 1994 in Jakobstad, Finland to a Finnish mother and a Finnish-speaking Swedish father, while being raised to speak only Finnish. Her parents were Baptist missionaries and Forsberg grew up a missionary kid. Because of her parents' career, she moved frequently as a child, living in Texas for five years and the United Kingdom for a year, before returning permanently back to Finland at age six. Forsberg spent a few years in a music academy in Jakobstad and later studied to become a chef before embarking on a singing career.
