Catherine Zeta-Jones Goes Undercover  7/30/07

Catherine Zeta-Jones took a job in a New York restaurant to prepare for her latest movie role - and went unnoticed.

The actress worked undercover as a waitress in the city's Flamma restaurant to prepare for a role in upcoming romantic comedy No Reservations - but refused to reveal her real identity to customers.

Waitress Ilona Rubenstein tells British newspaper the Sunday Mirror, "Some customers said she looked vaguely familiar from the TV or movies. Others told her she looked really like Catherine Zeta-Jones. But she just laughed and said she got that all the time and then walked away."
