Hougi's gal shows off dat ass!

Looks like Francois Hougaards' girlfriend isn't too shy to show off her behind!

The local model is in Italy with her Springbok boyfriend, where she took part in a beachwear photoshoot poolside in Pisa.

She stuck up some pics of the shoot on Instagram with one in particular catching our eye.

Captioning the picture "Ass in Pisa!", Chelsea posed with her back to the camera and her hands in the air showing off her bum and legs to her fans.

Nice ass!
