Justin Bieberhas tweeted to fans about having his "worst birthday" while out celebrating turning 19 in London last night.
The teen pop megastar had spent £10,000 on lining up a night to remember in the big smoke according to The Mirror, but it seems it ended up being an evening he'd rather forget.
He had [uuid=76684dfe-1cbe-4295-b0f9-13f8f2bfb628]arranged a circus-themed party[/uuid] at Cirque Du Soir and tweeted before the festivities began to say: "Gonna be fun tonight. Thanks to everyone for all the birthday wishes. 19!"
But he later updated his followers with the words "worst birthday" at 2am.
E! Online claims that he didn't stay very long at the club because there was a confrontation between his guests and security staff.
