Born Kathleen Emperatriz "Kat" DeLuna on November 17, 1987, in The Bronx, New York, Kat Deluna spent her earliest years in New Jersey before moving to her parents’ native Dominican Republic as a child. The family later relocated back to the states, and her parents divorced, compelling Deluna to write her first song, “Estoy Triste (I Am Sad.”
As a child, DeLuna trained as an opera singer, and compiled many musical influences because of her heritage and her exposure to many American genres As a freshman in high school, Kat responded to a listing in The Village Voice for an audition, and was selected to join an all-Latina, Hip Hop/R&B group called Coquette. Kat continued to search for solo performance opportunities. At age15 she entered a karaoke competition sponsored by Coca-Cola, where her rendition of Whitney Houston’s classic "I Will Always Love You" won the competition, and began to get her noticed. It was through this competition that Kat also met iconic Cuban salsa singer Rey Ruiz. Ruiz gave Kat advice as she started her career to take risks and put herself out there as an artist. Deluna began tirelessly writing her own music and has continued to do so since. Epic Records signed Deluna, and she is currently signed under Epic Records/GMB and Akon's label Konvict Muzik.
Kat Deluna released her debut album, 9 Lives, in August 2007. The album reached #58 on the Billboard 200 and her hit single, “Whine Up,” featuring Elephant Man, went to #29 on the U.S. charts and even higher on the charts of many other countries. Fellow performers Shaka Dee and Don Omar also collaborated on the debut album. In 2008 she released the single “Run the Show,” featuring Busta Rhymes. Deluna has continued to release singles off of 9 Lives, including “In the End” and “Am I Dreaming,” and is hard at work on her next album, which she is rumored to be working on with rap star Akon, among other producers.
