Justin Bieber might have been getting excited about his 19th birthday bash all week, but apparently it didn’t turn out quite how the pop star hoped.

In fact, at 2am this morning the singer tweeted, “Worst birthday.”

Rumours had been circulating all week that Bieber was planning an extravagant circus themed party that would set him back £10,000.

But according to eyewitnesses at London’s Cirque du Soir the night went south when Bieber’s entourage had a run in with the club’s security. E! reports.

Sources at WENN report that Justin was seen arriving at 2am, but left just five minutes later instead heading for McDonalds in Earls Court before heading back to his hotel.

Bieber's fans around the world quickly waded in, blaming paparazzi for their idol’s ruined night with ‘#BeliebersHatePaparazzi’ trending on Twitter.

Bieber apparntly decided the club was not to his liking

Last weekend Bieber found himself red-faced when a Manchester night club refused him entry because they didn’t want to tarnish their ‘edgy’ reputation.
