Justin Bieber looks for a Purpose as he arrives in Dublin

With a sell-out show in Dublin tonight, the crowd might be forgiven for wondering which Justin Bieber will show up, writes Ed Power

When Justin Bieber steps in front of a sell-out audience in Dublin tonight, his backroom team will be crossing their fingers that the concert goes off without a hitch. At a show in Manchester last week, the 22-year-old singer walked off after attendees refused to pipe down so that he could share some thoughts. A second hissy fit in a fortnight would bring further bad publicity at a crucial point in the career of a former teen heartthrob desperately seeking to rebrand as a grown-up artist.

“You can talk if you want,” Bieber had told the crowd, before letting go of the microphone and heading for the wings (in his defence he later returned). “If you guys wanna take this moment and — I just thought I could have a moment of, you know, trying to say something.”
