Dear Justin Bieber fans:

We know this young star is very cute and has a pretty good voice. But he's just a singer. Seriously, he hasn't cured a single disease or come up with financial regulation that will help ease the ongoing economic crisis.

It's necessary to pass along this message because people are starting to get seriously injured as a result of the mass hysteria surrounding Bieber. Even worse: police are shutting down his concerts!

Both these developments took place in Sydney, Australia over the weekend, as Justin was set to sing on stage for a morning TV show. But the performance was canceled after thousands of unruly fans created a security nightmare and at least 10 girls passed out.

Fans camped out overnight for the event. By 3 a.m., almost 4,000 people had gathered. When they heard Bieber might be in the vicinity, they rushed the stage, broke down barriers and generally acted like brides at a wedding gown sale.

Not even Tiger Woods acts this out of control inside a Las Vegas night club.

As news of the cancelled gig spread, Justin Tweeted: "I love my fans... and I am just as disappointed as everyone else with the news from this morning. I want to sing for my fans," adding in capital letters:

"I WANT TO MAKE THIS CLEAR...I DONT CANCEL...I WOKE UP THIS MORNING TO THE POLICE CANCELING THE SHOW FOR SAFETY REASONS."

Bieber then wrote he was "beyond grateful...for such an amazing warm welcome."

We're sure he is, but perhaps Justin should also send a message to his followers: Chill the eff out! I appreciate the support, but I have a bowl cut and I sing songs other people have written for me. That's about it.
