Nancy was born on May 16th 1983 in Ashrafieh, Lebanon. Since her childhood, Nancy loved singing. In 1995, at age 12, she participated in "Nojoum Al-Mustaqbal" (Stars of the future), a specialized television show for young talents. She won the gold medal in the "Traditional Lebanese" category.
Nancy released her first album at age 13. Mi7tagalak (1997) had 8 tracks and was the beginning of a very successful career. The clip for Mi7tagalak ranked number 1 for three consecutive weeks upon its release.

In 1999 she released her second album, Sheel 3younak 3anni with the help and guidance of her father as manager. Achieving success was however a long and tedious task.

Few years later, Nancy met Jiji Lamara who quickly became her new manager. Their collaboration resulted in the release of the highly acclaimed third album: Ya Salam. Akhasmak Ah, the first single to be released was a huge success. The video clip, directed by Nadine Labaki, gave Nancy a totally new image and look. Two additional mega hits, Ya Salam and Yay were also made into video clips.
