Justin Bieber has let loose in a Twitter tirade, calling out his haters.

And what the 19-year-old had to say Wednesday was a lot longer than 140 characters! He actually fired off a dozen tweets defending himself against "rumors."

The Biebs' rant came two days after he reportedly showed up for a concert at London's O2 Arena two hours late - a big problem for an audience full of kids out on a school night.

Afterwards, there was speculation that the local government might fine Bieber for keeping the concert going so late, and some reports claimed that the reason he was tardy to the stage late is because he was partying too hard.

The controversy prompted the singer to apologize to his Beliebers on Tuesday, citing technical issues as the reason for the delay.

"i was 40 min late to stage. there is no excuse for that and I apologize for anyone we upset. However it was great show and Im proud of that."

Bieber was two minutes early for his Tuesday night performance — the second of four at the O2 this week — according to the venue's official Twitter account.

However, Bieber is obviously still upset about the first show.

Check out his tweets.

Glad he got that off his chest!
