That's brrrave! Justin Bieber wears nothing but his wet Calvins after jumping into a glacial lake in Iceland

Baby, it's cold out there.

Justin Bieber is really taking his role as the face - and body - of Calvin Klein to a new extreme wearing nothing but his tighty whitey's to plunge into icy water in Iceland on Tuesday.

While the act of jumping into a lake formed by a melted glacier is fearless enough, the 21-year-old was even more fearless when he had completed his freezing swim - emerging in the wet and clinging underwear.

Not only that, the Baby singer was willing to not only pose for a snap, but also post it on his Instagram.

While there were once rumours that Justin had sought the help of Photoshop to make himself look a little better in his underwear it looks like there was not any technical wizardry after all.

Either proud of himself for jumping in the freezing lake or proud of how he looks in just his boxer briefs, in the picture the singer is absolutely beaming as he emerges from the lake.
