DON'T TOUCH JUSTIN TIMBERLAKE

Justin Timberlake's fans have been told they can "touch" but not "grab" the singer. The singer's security team reportedly laid down the strict instructions to people in the front row of his 'Future Sex Love Sounds' tour. A source said: "They were quite specific about what was and what was not allowed. We've never known anything like it. It was hysterical." Despite the stern warnings, Justin - who kicked off his UK and European tour at Belfast's Odyssey Arena on Tuesday was joined on stage by two men.The source added: "Justin looked a bit perturbed. Far from concentrated on singing he was looking all around as the action unfolded." The men had splashed out on exclusive tickets for the SexyBack Dance Club - a private area right in front of the stage. It was reported they mocked Justin before the singer's burly bodyguards forced them off the stage. Justin, who is touring with hip-hop mogul Timbaland, is also set to perform in Glasgow, Manchester, Paris, Munich, Milan, Berlin and Amsterdam.
