Lady GaGa has been forced to cancel her Indonesian concert, as promoters claim the threats made against her were too serious for the show to go ahead. The Born This Way Ball, which was scheduled to take place on 3 June, has been at the centre of a campaign from Islamic hardliners, claiming the show could undermine the country’s moral fibre. Promoters had suggested negotiations were taking place to tone down the gig, ensuring it could go ahead safely, but the pop diva’s management stated there would be no compromise to quiet the religious conservatives. GaGa tweeted an apology to her fans.
