Justin Bieber has added an Irish date to his upcoming 'Believe' world tour.

The teen star had previously confirmed a batch of England dates due to take place early next year.

They were announced in addition to a mass of North American concerts, which will run from September through to January 2013.

Bieber has now confirmed a concert at Dublin's O2 on February 17.

It will take place four days before the Canadian hits the UK, with his run of dates in England starting in Manchester on February 21.

The 'Believe' star meanwhile recently unveiled the video for his latest single 'As Long As You Love Me', which features Reservoir Dogs hardman Michael Madsen beating up Bieber.

Madsen, however, admitted that he didn't find it very fun clashing with the singer because he was so nice on set.
