So we told you on Friday Justin Bieber was throwing himself a HUGE 19th birthday party in London; it was circus themed with clowns, jugglars...everything! He even flew out 20 of his friends for the whole event! But  he and his entourage were forced to leave the London nightclub after there was a problem with someone drinking underage...Jaden Smith (Will Smith's kid) who is only 14!

The club wanted to kick out Jaden but Justin wouldn't leave his friend stranded all alone in London so he and his entire entourage got up and left! Justin was upset with the club and ended up at a nearby McDonalds and went right back to his hotel, tweeting "Worst Birthday".

I wouldn't cry for him though, because he also left the club that night with super hot British singer, Ella-Paige Roberts Clarke!
