Did Audrey Hepburn place her hand in the mouth Rome?

You're likely thinking of the iconic scene in the movie Roman Holiday where Audrey Hepburn's character, Princess Ann, places her hand in the mouth of the Mouth of Truth statue in Rome.

This is a popular tourist attraction in Rome, and the legend is that if you lie while placing your hand in the statue's mouth, it will bite your hand off.

While the statue itself is not actually called "Rome," it's quite possible the legend of the Mouth of Truth contributed to this confusion.
