Charlie Mulgrew tweets picture of naked lookalike

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.
