It's a glamourous business being an A-list Hollywood actress – just ask Natalie Portman who got to roll around on the floor in a chavy outfit for her craft on Wednesday.

The actress got down and dirty while filming a fight scene in which her character Nichole helps defend a young boy against a bully.

For her role in Hesher, Natalie also gets to wear a fetching wardrobe of cheap vest tops and skirts, and thick, NHS-style spectacles.

The film centres on a teenager struggling to piece his life back together after his mother dies.

It was all a far cry from Natalie's eye-catching display at last week's White House Dinner.
