Anne Hathaway left a bag of dog skitter on a photographer's car.

The actress was out walking her dog Esmeralda in Los Angeles on Thursday when she was spotted by the paparazzo who took a few shots of her with her canine friend.

However, it seems Anne was slightly unhappy about being seen and so, when her chocolate Labrador mutt needed to answer the call of nature, the 31-year-old actress decided to use the pooch's poo as a dirty protest.

Anne bagged up the fresh faeces and placed it on the windshield of the snapper's white Toyota.

The actress - who is married to Adam Shulman - and her pet pooch then walked off and returned home.

It is not known if the unnamed paparazzo complained about the package left on his car or whether he disposed of it accordingly.
