Christophe Durier better known as Christophe Willem (born 3 August 1983 in Enghien-les-Bains, Val-d'Oise), is a French singer and the winner of the fourth edition of Nouvelle Star (French version of Pop Idol) in 2006.
Christophe 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.
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.
