More than 100 artists have signed a pledge of support for Lorde after she was criticised for deciding not to perform in Israel.
The letter, published in The Guardian on Saturday, was signed by a range of people including film director Ken Loach, musicians Brian Eno and Roger Waters and actors Mark Ruffalo and John Cusack.
"We write in support of Lorde, who made public her decision not to perform in Israel and has now been branded a 'bigot' in a full page advertisement in the Washington Post," it read.
"We deplore the bullying tactics being used to defend injustice against Palestinians and to suppress an artist's freedom of conscience. We support Lorde's right to take a stand," the letter, written and promoted by Shmuley Boteach said.
On Christmas Day Lorde cancelled a concert scheduled for Tel Aviv's 15,000-seat Convention Centre on June 5 after criticism from activists in the BDS (Boycott, Divestment, Sanctions) movement.
