There’s a scenario for some fetishist here somewhere:

She may be an international movie star, but this impudent pooch can’t tell the difference between Natalie Portman and a fire hydrant.

The “Star Wars” cutie was the unfortunate victim of a surprise soaking as she dropped by a downtown dog run.

Portman, who has been spotted in the West Village in recent days with her bearded boyfriend, Venezuelan-born folk singer Devendra Banhart, was walking her dog with him yesterday when the brazen piddling took place.

While she was getting a pup’s-eye view of the surroundings from ground level, another stroller’s frisky pet raised its hind leg, relieved itself right on her shoes — and then ambled on its way.
