Kat DeLuna was born on 26 November 1987 in Bronx, New York. Soon after she was born, Kat’s family moved to the Dominican Republic. Since childhood, DeLuna was dreaming of becoming a singer. She was a big fan of Aretha Franklin. In 1996, the family moved back to the United States. This time, they settled in Newark. Kat’s parents soon divorced. In her first song “Estoy Triste”, the singer talked about her hurt feelings and explained how tough it was to listen to her parents fighting.
After the divorce, the family had financial troubles. Kat’s sisters tried earning money by performing in local plays and festivals. These gigs helped the family survive. They also allowed Kat to perform with such celebrities as Marc Anthony and Milly Quezada.
When DeLuna was 14, she enrolled in the school of arts, dreaming about a singing career. Soon she was noticed by a label, J Records. Kat was invited to perform with the girl band, Coquette. A year later, she won a karaoke contest sponsored by Coca Cola. At the contest, she sang "I Will Always Love You". After that performance, a singer Rey Ruiz told Kat that she had a big future as a solo singer.
