Novak Djokovic And Rafa Nadal Enjoy Tennis On Argentinian Glacier (VIDEO)

First it was Kate Upton getting all sporty - kind of - in the Antarctic, now it's the turn of the greatest two tennis players in the world to head into the deep freeze.

Novak Djokovic And Rafa Nadal enjoyed a knockabout aboard a boat near one of Argentina's most famous tourist attractions, the Perito Maruno glacier.

Like Kate in Antarctica, the temperatures didn't seem to bother them though, wearing their usual tennis gear as they walloped balls into the icy waters.
