It's easy to get a little carried away when you're in close proximity to a hottie like Justin Timberlake. That's why the singer's security team had laid down the law for his tour -- especially for fans who shelled out extra dough for entrance to the SexyBack Dance Club, a VIP area surrounding the stage that puts you so close to Justin that spit might land on you as he sings. Rule number 1: you can touch, but you can't grab. "They were quite specific about what was and what was not allowed," a source tells FemaleFirst UK. "We've never known anything like it. It was hysterical."

Undeterred by the warning, two men at a European show this week jumped onstage with J.T.! "Justin looked a bit perturbed," the source says. "Far from concentrated on singing he was looking all around as the action unfolded." The intruders reportedly mocked Justin until bodyguards forced them offstage.

OK -- first girl to send us a piece of Justin's shirt gets $1 million! (Haha, just kidding. If we had that much cash, we'd have ourselves a private Justin concert.)
