Yvette Baheux, better known by her stage name Betty Mars, was a French singer and actress.
The youngest of ten children, she developed an early aptitude for dance and acrobatics. When she was sixteen, she was already part of a revue, and traveled across Europe and the Americas for performances. In 1971, she released her first song, "Monsieur l'étranger", which the composer Frédéric Botton offered her after seeing her at a cabaret. It ended up being a commercial success.
The following year, she was selected to represent France at the Eurovision Song Contest 1972 with the song Comé-comédie, which placed eleventh out of eighteen entries. Nevertheless, she continued to record songs during the 1970s, including duets with Mike Brant and Alain Barrière. Betty Mars also transitioned into acting, one of which included a softcore porn film, Emilienne.
Despite preparing a concept album revolving around the French Revolution, Betty Mars' financial and personal problems led her to jump out of a window from her apartment on 31 January, 1989. She died three weeks later at the age of 44, leaving behind one daughter.
