Naomi Campbell has shown a previously unheard of humble side by turning tea girl on the set of TV show Ugly Betty.

The tempestuous supermodel shocked onlookers by taking it upon herself to help out whilst making a cameo appearance on the show.

A source tells the News Of The World, "It was amazing to see. She served drinks and snacks to people and even remembered to say please and thank you. All this without prompting."

She obviously really needs the work!
