He performed at the RDS arena here.
The 23-year-old looked cool and casual when he met the fan, but appeared to mix up the country with Scotland as he donned a pair of red tartan trousers, reports dailymail.co.uk.
Slinging his arm around the fan, named Mark Smith, Bieber smiled and chatted away as though he was an old friend.
In some photographs, Smith can be seen holding his hand over his mouth in disbelief as Bieber was strolling with him on the streets.
