Béatrice Martin (French pronunciation: [beatʁis maʁtɛ̃]; born September 22, 1989), better known by her stage name Cœur de pirate ([kœʁ də piʁat]; French for Pirate's Heart), is a Canadian singer-songwriter and pianist. A francophone from Montreal, she sings mostly in French and has been credited in Montreal Mirror with "bringing la chanson française to a whole new generation of Quebec youth".
On February 29, 2012, Martin announced on Twitter and Facebook that she was expecting a girl with her fiancé, Alex Peyrat, a tattoo artist. Martin and Peyrat were married later that year on July 26 and their daughter Romy was born on September 4.
On June 16, 2016, in an op-ed for Vice magazine's Noisey, Martin came out as queer as a response to the shooting at Pulse, a gay club in Orlando. The following day, she announced that she was filing for divorce from her husband. At the time, she was known to be in a relationship with Laura Jane Grace, who fronts Against Me!, although they later broke up. Martin and Peyrat remarried in March 2017.
