Naomi Campbell back at work for throwing her phone

On Monday when Campbell showed up, paparazzi zapped photos of the model as if she was headed for a runway show.  Instead, inside she traded in her heels and sweater for a pair of work boots and a bright orange vest - just like everyone else doing their time.

Naomi is being praised for a job well done.

An employee tells British newspaper The Sun: "She worked really hard and asked the supervisor, 'How am I doing?' He told her she was working harder than some regular staff.

"But some of the women who work here have been a bit catty and say they are going to make extra mess for her to clean."

If Naomi refuses to do any of her duties which will include mopping floors, scrubbing toilets and taking out trash - she'll be sent back to court.

Campbell has been sentenced to work with the sanitation department through Friday.
