Haddad, 32, is a Paris-born dentist who immigrated with his family to Israel when he was eight years old.
Two years ago, he competed in France's version of "The Voice," coming in third place. Since then, he has become a popular singer in France and a year ago he released his first single under the moniker "Amir."
Haddad will attempt to reclaim France's lost musical fame at the European singing competition, most likely with the upbeat song "J’ai Cherché" ("I Searched For"), which was debuted on French TV on Thursday.
The French song selection has been kept secret this year and was supposed to only be revealed next month, but the host of a popular show on a private French TV channel decided to blow the lid off the song selection.
Because France is one of the Eurovision's founding countries, Haddad will not have to compete in the semi-finals and will advance directly to the finals.
Haddad's family immigrated to France from Tunisia and Morocco. As a boy he sang in synagogues and family events. He is married to an Israeli woman called Lital.
