Marie Claire is best known for the single "Falling Into You" which was written and originally performed by Marie Claire, but later covered by Celine Dion; the single was to become the title track for Celine's album. Incredibly, the original backing track recorded by Marie Claire, along with her own backing vocals, is the version used by Celine.

During the late 1990s and early millennium, Marie Claire often performed live in London at The Kashmir Klub and The Bedford, performing the tracks she had written for herself and other artists.     As far as is known, Marie Claire is still living in London with her husband and child, and preparing her next solo album in collaboration with Indian musician Shrikanth Sriram (Shri from Badmarsh & Shri.)
