Naomi dresses to impress as she completes cleaning order

Naomi Campbell finished her cleaning duty in true supermodel style tonight, stunning onlookers by leaving New York’s sanitation department in a sequin encrusted floor-length silver evening gown.

The catwalk star, who spent five days mopping, sweeping and scrubbing toilets, drew grasps from the photographers when she emerged into the drizzle in the show-stopping frock before speeding away in a Rolls Royce.
