London: Singer Bryan Adams is reportedly barred from performing at a memorial concert for Diana, the late princess of Wales, for fear that his presence might incite media attention over his secret fling with her. Adams was involved with the princess almost a decade ago and it became public only after her death in 1997 when she died in a car crash. Diana’s children, princes William and Harry, have banned the Everything I Do rocker from appearing at the concert to make sure that gossip doesn’t overshadow the concert, reports contactmusic.com. “The princes have nothing against Bryan Adams... But they want the concert to be free of any innuendo or tittle-tattle. It was decided that it would be inappropriate for Adams to appear,” a source said.
