Supermodel Naomi Campbell, wearing black stilettos and slinging combat-style boots over her shoulder, traded the catwalk for community service at a sanitation garage on Monday. Campbell arrived at the Manhattan District 3 Garage at Pier 36 on the Hudson River in a black SUV at around 8 a.m. For five days, Campbell will push a broom or a mop at the garage to fulfill her sentence of community service for throwing a cell phone at her maid. She was met by an official of the garage who escorted her through the steel double doors of the building. Her ensemble also included chocolate brown pants, a short fitted coat with a flared bottom, dark sunglasses and a newsboy-type cap over a short hairdo. She did not acknowledge the media horde.
