Justin Bieber, who we all know is a pop-star of almost demigod proportions, was in town last night for a concert in The O2 - and Ireland's tween population was out in force to welcome the Canadian tyke to Dublin. Scroll down for our pictures.

Bieber, who is currently in the middle of his Believe tour, played a twenty song set in Dublin last night and will play another tonight before jetting off to the UK for a twelve date stand with mainland Europe to follow.

Some Bieber fans already queuing outside The O2 for tonight's performance, with some camping outside the venue since 7am on Saturday morning. It takes a certain level of commitment to be a Belieber, that's for sure.
