Justin Timberlake’s fans have been told they can “touch” but not “grab” the singer.

J.T’s security team reportedly laid down the strict instructions to people in the front row of his ‘FutureSex/LoveSounds’ tour kickoff in the UK.

“They were quite specific about what was and what was not allowed. We’ve never known anything like it. It was hysterical,” says a source.

Two men who had splashed out on exclusive tickets for the SexyBack Dance Club, a private area right in front of the stage, mocked Justin before the singer’s burly bodyguards forced them off the stage.

“Justin looked a bit perturbed. Far from concentrated on singing he was looking all around as the action unfolded.”
