Justin Bieber celebrated his 19th birthday in London over the weekend and later tweeted that he had the "worst birthday". OH NO!

So, Justin booked his party to take place at this really cool club in London. Bieber was turning 19 and the legal drinking age in the United Kingdom is 18 so, there were no problems for Justin and most of his friends. However, when good friend Jaden Smith (Will Smith's son) tried to show up at the club at a young 14, the bouncers said they couldn't give her clearance to enter.

The club apologized to Justin, who took his friends to McDonald's and on some other age appropriate adventures and then went back to the hotel.

Justin reportedly spend about 12K on the party. No word on if he'll be refunded.
