A naked woman sunbather caused traffic chaos in Vienna when she positioned her bum outside of a window to catch some rays.

A photo circulating online shows the woman with her legs dangling out of a third floor window in the Austrian capital while attempting to get some sun where it normally doesn't shine.

Her antics caused a 3 car pileup after motorists in front took their eyes off the road to glance up at the view.

Several cars were blocking the road by the time police arrived - but by then she had disappeared inside and closed the windows.
