Thalia started singing professionally when she was 10 years old, as she joined the kid singing group Din Din. She had also moved to Los Angeles during the eighties. In 1983, she started acting, and in the following year she joined Vaselina and the musical group Timbiriche where she was a backup singer. Thalia started acting in musicals including Grease, and when the lead singer of Timbiriche left the band, she ended up becoming the lead singer. In just a few years, Thalia was able to establish herself securely in both the acting and music industry. In 1987, she began acting in telenovelas, her first being Pobre Seniorita Limantour.
In 1990, Thalia released her first album which was self-titled. In 1992, she also started working in a string of soap operas which were built around Maria. These included Maria Mercedes, Maria Mar, and Maria del Barrio, which helped catapult her to international recognition and gave her the nickname The Queen of the Telenovelas. Thalia had also switched labels, leaving Fonovisa and signing up with EMI Latin, which was followed by a second album entitled En Extasis. This was only the beginning of a very successful career, as she began to collaborate with producer Emilio Estefani Jr.
Emilio Estefan was responsible for producing En Extasis along with her other albums, Amor a lo Mexicano, and Arrasando. Each album just became bigger, more popular and stronger than the last. Her many hit singles included Piel Morena, Maria Del Barrio, and Entre el Mar y una Estrella. Many of Thalias singles made it to the Billboards Hot Latin Tracks chart. Thalia also owes her huge success to working with Estefano, a popular songwriter and producer. He helped write and produce her 2002 album, Thalia, and was also responsible for other stars success including Enrique Iglesias and Chayenne.
Many of her songs made the top of the charts, and starting the 2000s, Thalia tried her hand in English songs. Her successs just kept on growing during this time, and it was also largely in part to her marriage to Tommy Mottola, who was the head of Sony Music at the time. They had a famous three million dollar wedding.
