Early Life & Background

Jérémy Chatelain was born on October 19, 1984, in Créteil, Val-de-Marne, France, to parents Philippe Chatelain (a French garage director) and Maria Chatelain (of Spanish Sephardi Jewish descent).

His mixed French-Spanish ethnicity and Jewish family background shaped a close-knit upbringing in the suburban town of Étiolles near Paris, alongside an older brother, Julien Chatelain, who shared his passion for fashion, and a younger sister, Amandine Chatelain (born in 1990), drawn to theater.

From a young age, he displayed strong musical talent, studying piano from age five, later adding drums and guitar at a local conservatory, while also exploring theater in school.

Academically capable, he earned his baccalauréat but abruptly left high school in 2002—at just 17—to audition for the second season of Star Academy, famously lying about his age to meet the entry requirements.

Career

Jérémy Chatelain began his career at 17 in 2002, joining the second season of Star Academy on TF1. He quickly stood out for his grunge-inspired style, charisma, and originality.

Although he was eliminated after several weeks, he joined the show’s tour in early 2003, performing across France, Belgium, and Switzerland with other contestants. That same year, he launched his solo music career with a self-titled debut album, also known as Nouveau-né, featuring rock songs he wrote and composed.

Singles like “Laisse-moi“, “Belle histoire“, “Vivre ça“, and “J’aimerai” saw moderate success in France, and he toured widely, including shows with the group L5 and solo performances in 2004. Alongside music, Chatelain launched his clothing line, Sir Sid, in 2003, with the first collection hitting stores in 2004, demonstrating his interest in fashion and design.

His second album, Variétés françaises, came out in March 2006, led by the single “Katmandou” and followed by songs like “J’veux qu’on m’enterre“. He promoted the album with appearances on summer tours, including “L’été Française Des Jeux – Tournée Des Plages RTL“.

After this period, Chatelain moved away from performing as a solo artist and focused on production and composition. He worked closely with his then-wife, Alizée, on her albums, especially her 2007 comeback, Psychédélices.

He also collaborated with artists such as Oxmo Puccino, Emma Daumas, and later with electronic musicians on the Ed Banger label, including Busy P, Boston Bun, and Point Point.

In 2015, he co-founded Threesome Studio, where he worked on music for advertising campaigns for brands like Google and Kenzo. He released the single “Je me rappelle” in 2017 and continued collaborating with others into the 2020s, remaining active in music composition and production.

Personal Life

Jérémy Chatelain, born on October 19, 1984, is 41 years old.

He married singer Alizée on November 6, 2003, in Las Vegas, shortly after meeting her in March 2003 during a promotional tour following Star Academy. Their marriage lasted until their separation in 2011 and official divorce in 2012, a period Alizée later described as difficult, feeling they had grown apart after starting so young.

The couple shares one daughter, Annily Chatelain, born on April 28, 2005. Since around 2018, Chatelain has been in a long-term relationship with Julie Favre, with whom he welcomed a son, Forest Chatelain, born on May 27, 2018.

Despite the divorce, he and Alizée have maintained an amicable co-parenting relationship, as evidenced by recent public interactions into 2025.

Height is 1.71 m.

Net Worth

Jérémy Chatelain‘s net worth is estimated at $100,000 to $250,000.

This modest figure reflects his early success as a solo artist in the mid-2000s, including album sales and tours following Star Academy, as well as income from his short-lived fashion line, Sir Sid, and subsequent behind-the-scenes work in music production and composition.

As a lesser-known figure in the industry today, with no major ongoing public ventures, reliable sources indicate his earnings remain in this lower range compared to more prominent French celebrities.
