She attended Benjamin Franklin Elementary in Newark, and was taught by Nicholas Straus. DeLuna then attended the Newark Arts High School, which was the only school she applied to. While there, DeLuna and her friends formed an R&B group called Coquette. DeLuna had a tough upbringing and was raised in poverty. She spent her time listening to Aretha Franklin and Billie Holiday records, which she imitated daily on her karaoke machine.
At age 15, DeLuna entered a Coca-Cola sponsored karaoke competition. Her version of "I Will Always Love You" took first place. It was through this competition that she met Cuban salsa singer Rey Ruiz. Ruiz gave DeLuna this advice: "Nobody knows you better than you do, and nobody can help you if you can't help yourself." DeLuna began writing her own music and has continued to do so. In 2004, while DeLuna was 17, Coquette opened for a Cassidy concert in New Jersey. In 2006, DeLuna chose to pursue a solo career and was signed by Epic Records.
She has a critical, cynical attitude towards many religions and philosophies. Without realizing it, she prevents herself from appreciating new viewpoints and attitudes. DeLuna is rigid and dogmatic.
