Celtic defender Charlie Mulgrew tweeted a picture of a nude couple late on Sunday night.
The 27-year-old's motive for sharing the image, which was taken by Norwegian photographer Petter Hegre, is unknown.
However, the pictured male shares a strong upper-body resemblance with Mulgrew, who has over 80,000 followers on Twitter.
