Hollywood beauty Catherine Zeta-Jones has been working in a restaurant as research for her new movie.

The 37-year-old will play a top chef in No Reservation but insists she needed the real life research after setting fire to a pan the first time she tried to cook a meal for her husband Michael Douglas.

And the Welsh actress is determined to leave her superstar baggage behind in her new job.

She says, "I worked the kitchen as well as the floor."

"I had some of the worst clients, the really arrogant ones."
