Sylvie Vartan (born Sylvie Georges Vartanian; 15 August 1944) is a Bulgarian-French singer and actress. She is known as one of the most productive and tough-sounding yé-yé artists. Her performances often featured elaborate show-dance choreography, and she made many appearances on French and Italian TV. Yearly shows with then-husband Johnny Hallyday attracted full houses at the Olympia and the Palais des congrès de Paris throughout the 1960s and mid-1970s. In 2004, after a break in performances, she began recording and giving concerts of jazz ballads in francophone countries.
Vartan was born in Iskrets, Sofia Province, then Kingdom of Bulgaria. Her father, Georges Vartanian (1912–1970), was born in France to a Bulgarian mother and an Armenian father. He worked as an attaché at the French embassy in Sofia. The family shortened the name to Vartan. Her mother, Ilona (née Mayer), daughter of prominent architect Rudolf Mayer, was of Hungarian Jewish descent..
