Jane Birkin, the British-French singer and actress whose collaboration with the artist Serge Gainsbourg made her a defining figure of the 1970s and whose personal style inspired a luxury handbag, died on Sunday in Paris. She was 76.

Her death was confirmed by French President Emmanuel Macron, who called her “a French icon” in a message posted on Twitter. The French news media reported that Birkin had been found dead at her home but that the cause was not immediately known.
