Yaire (real name Yaidelice Monrouzeau) was born on 29 July 1977 in San Juan, Puerto Rico. Yaire’s father Eloy Monrouzeau was a famous figure in the music world. That is why the girl got a chance to show her talent at a very young age. When Yaire was just 13 years old, she was already writing songs for celebrities. It was Yaire, who wrote lyrics for the famous Olga Tanon’s song "Bésame agresivamente."
A year later, another song written by Yaire for Tanon “Contigo o sin ti” became a big hit. A while later “Mujer De Fuego”, also written for Tanon, brought Yaire an ASCAP award (American Society of Composers, Authors, and Publishers). She was the youngest author to receive such an award.
For a long time, Yaire continued writing songs for Spanish-speaking celebrities, such as Gisselle and Melina Leon. She wrote such songs as "Quiero que me beses toda", "No te olvidé," and "Gaviota herida." In 1999, Yaire received one more ASCAP award for a hit song "El frío de tu adios," which was performed by Olga Tanon. Yaire was becoming more and more popular. It was prestigious to book Yaire’s lyrics-writing services.
Soon Yaire decided to try her luck on stage. When she turned 21, the songwriter recorded her first LP Formas De Vida. The album was very successful and received positive reviews from the critics. When recording the LP, Yaire worked as a songwriter, composer, and singer.
