Before her career in show business she worked as a photo lab technician, a dental assistant and a tourist guide in Italy.
She made her first single releases in collaboration with Schairer and the composer and producer Jean Frankfurter as well as the lyricist Erich Offierowski.
Since November 2007, Claudia Jung has been the protector of a childcare project for traumatized children who have lost faith in themselves, other people and the surrounding world.
In 2008, she debuted as actress, appearing as the female lead in the television series of the ARD (First German channel): Das Musikhotel am Wolfgangsee (The Musical hotel on Lake Wolfgang).
On 2 March 2008 Claudia Jung - officially Ute Singer - was elected as representative of the group Freie Wähler in the county council of Pfaffenhofen.
In early 1994, Claudia Jung, following a bad fall from her horse (equestrianism is her favorite sport), suffered a double fracture of the skull base.
Her comeback in September of that year, with the song "Je t'aime mon amour" in tandem with the pianist Richard Clayderman, however, was phenomenal.
