Reykjavik: Pop star Justin Bieber wore nothing but a pair of white boxers to take a dip in a lake in Iceland.

The singer shared an image of himself dressed in his bright white Calvin Klein underwear giving a high-five to someone who was out of view, reports mirror.co.uk.

The star, who was sporting a massive grin, had his six-pack and huge tattoo collection on full display in the photograph.

Proud of his ripped body, the star then took to Instagram to share the shot with his 39.3 million followers.
