Perez Hilton News: London Nightclub Responds To Justin Bieber's "Worst Birthday" Drama.

Well, we guess the lesson that we all should take from this is that rules are rules…

Even if you're Justin Bieber, and those rules result in your having the "worst birthday!"

As we've reported, the pop sensation was hoping to ring in 19 with a $15,000 celebration held at London's Cirque Du Soir, until the club's security guards refused to admit members of his entourage - including 14-year-old Jaden Smith(what will Will and Jada SAY?!) - because they were under the UK's legal drinking age limit of 18!

And while this refusal was enough to send the Biebs and his entire party packing up early, a spokesperson with Cirque stands by the guards' decision - because it's the LAW!

They say in a statement:

"We, like all clubs in London, operate a strict age policy. As a few of the members of the party were under the suitable age of 18, the security team at Cirque Du Soir, London, clearly explained this rule and refused entry to the club for anyone who could not provide us with adequate proof of age. Justin Bieber visits Cirque Du Soir regularly, and he and his friends are always welcome, as long the members of the group are legally old enough to enter the club. This was simply a matter of regulation that we must adhere to."

We are very sorry, and understand it's his birthday, but our hands are tied with local authorities and rules we need to follow as club to keep our license. We clearly didn't want to give him the 'worst birthday.' He is a friend and previously was always welcomed with open arms."

Well! Guess then means they didn't check with the club before they organized the party to include underage guests! Read more>>>> perezhilton.

What Happened? Jaden happened

According to new reports, the 14-year-old son of Will and Jada arrived to celebrate shortly after the rest of Biebs' crew, but would not be allowed in due to his age!

So after attempting in vain to get his pal through the doors, Justin apparently didn't feel it was right to keep the party going, so instead decided to call everything off and head back back to his hotel with his pal and some fast food from McDonald's!

Awww!

It's unfortunate that arrangements weren't made with the venue to accommodate guests of all ages, but how Justin handled it all really says so much about his character!

Very mature, boy! And you're only just freshly 19!

Thanks for being such a good pal to Jaden! We're sure it meant the world to him!
