Yvonne Constant was born on the left bank of Paris. She began her career as a ballet dancer, but because of her comedic flair and charismatic personality, the other dancers urged her to become a musical comedy performer instead.

Yvonne was cast to play multiple roles for the Broadway production of "La Plume de Ma Tante" and won a Tony award. When she did "The Gay Life"  with Barbara Cook, Yvonne received a New York Drama Critics Citation as on of the season's Most Promising Actresses.

Because of her quick wit, dynamic personality, and ability to do repartee, Johnny Carson had Yvonne on his show a record 45 times! Richard Rodgers saw her on the Tonight Show and immediately chose her for a principal role in "No Strings". After "No Strings" Yvonne played the French au pair in the Broadway Comedy, "Come Live With Me".

In the movies, Yvonne Constant is best remembered in Disney's "Monkeys, Go Home!" with Maurice Chevalier. More recently, she played the French chanteuse, Annette, in the television mini-series "Sins" with Joan Collins. All of Yvonne's movie performances are now available on DVD.

In addition, she has narrated or dubbed over 20 French movies including the much acclaimed, "Parfait", and was also the voice of Simone de Bauvoir.

In 2007, Yvonne was one of the stars in the City Center rival of "Follies"  in New York. She received 14 rave reviews for her rendition of "Ah, Paris!"

Yvonne's memorable one woman show, "Yvonne Constant Sings Yves Montand" was standing room only in theatres and concert halls in New York, Chicago, and Washington D.C.

Yvonne has sung in cabarets, hotels, and supper clubs in Europe and many American Cities to consistently outstanding reviews.

In recent years Yvonne has performed in several cabaret venues in the New York Metropolitan area including The Reprise Room, Danny's Skylight Room, The National Arts Club and the critically acclaimed Metropolitan Room where she appears regularly always with constantly updated shows. For many years her shows have been presented by Cabaret Legend Jan Wallman and her music director since 2006 has been the multi faceted Russ Kassoff.

Yvonne was named Chevalier des Arts et des Lettres by the French Government, and she maintains residences in both New York and Paris.
