Yang Yang and Long Hui, have been busy making babies, drawing crowds at Vienna’s Schönbrunn Zoo despite days of non-stop rain.

The pair surprised everyone in 2007 when Yang Yang give birth to her first cup Fu Long, (who is now is Bifengxia) after a successful natural mating in the spring of that year.

"Science has it pandas are generally reluctant when it comes to mating and very poor lovers – but try telling that to this pair. We simply can't stop them," laughed one keeper.

Lets hope for another brother or sister for Fu Long
