Christophe Frédéric Durier (French pronunciation: [kʁistɔf fʁedeʁik dyʁje]; born 3 August 1983), better known by his stage name Christophe Willem (French: [kʁistɔf wilɛm]), is a French singer and the winner of the fourth edition of Nouvelle Star (French version of Pop Idol) in 2006.

Willem spent most of his life in Deuil-la-Barre (Val-d'Oise), where his parents run a driving school. As a child, he learned figure skating and to play the piano. Later he learned to sing as part of a gospel choir "Young Voices". He also was composing songs at the age of fourteen.^{[citation needed]}

Before deciding to study to become a lawyer and calculus professor, he continued to practice music and in 2004 he appeared in a Richard Anconina film, Alive, where he played the role of Henri, a young man with a golden voice who is, nevertheless, not considered suitable for the lead role in a musical. Since his film career continued after this, he returned home, where he studied communication while working a number of part-time jobs, such as babysitting and helping in a theatre.^{[citation needed]}

Pushed by his family and friends, he decided to try out for the 2006 edition of Nouvelle Star. With an initial audition performance of Strong Enough by Des'ree, he surprised the judges, who did not expect such a quality voice from an admittedly ungainly-looking man. Nicknamed "La Tortue" (The Turtle) by Nouvelle Star judge Marianne James, he proved to be a popular contestant, and on 8 June, was crowned the fourth Nouvelle Star.^{[citation needed]}
