"Everyone keeps asking me where I will be today…gonna be at the Mayfair Hotel in London at 6.30 to party with the bosses."
Hundreds of girls showed up outside the Mayfair and Bieber was rushed out the back door into a car without being able to see them! He Tweeted his apology:
"Wish I could have come out from the performance at the mayfair but security wouldn't let me. For those girls who cursed me out for it."
"I'm sorry but sometimes I need to listen to security so no one gets hurt. But I like your attitude. The UK goes hard."
It's Bieber-mania everywhere!
