The pop superstar is currently in Australia as part of his 'Believe' world tour and used the opportunity as an excuse to get another striking tattoo, which he incorporated into the sleeve on his left arm.
On Saturday he tweeted, "just got off stage bout to get tatted" and followed the announcement up with a series of snaps of himself showing off his six pack and his latest piece of body art.
One of the pictures shows Justin,19, sat in the tattoo parlour with his hand on his head while the artist gets to work on his new design.
He then posted a handful of additional photos, each flaunting the large new eagle on his shoulder.
Next to one of the snaps Justin wrote, "fresh new tat", while another picture (in which he is actually covering his chest!) is intriguingly captioned: "Lets be honest".
Last month the singer revealed that he was shooting his latest music video for 'All That Matters' with model Cailin Russo as his leading lady, by uploading an intimate photo of Cailin kissing him on the cheek.
But it seems he and Cailin get even closer in the official visual, as the teaser (which was released last week) shows thing getting more than a little steamy between the pair.
The full length 'All That Matters' video is set to be released later today (2 December).
Watch the teaser below.
