Julia Roberts at the 36th Film Society of Lincoln Center's Gala Tribute Honoring Tom Hanks at Alice Tully Hall. New York City, USA - 27.04.09

The Hollywood star is mother to three kids with husband Danny Moder - twins Hazel and Phinnaeus, four, and Henry, two - and deliberately refuses tell them she is an actress.

She tells British magazine New, "They don't know what I do - yet. I kind of like it that way. I don't know what they're going to ask me when they do realise and I don't know what I'm going to tell them, because I want movies to stay special for them for as long as possible."

And the star admits she has already lied to Hazel about the secrets behind the film-making business.

She adds, "My daughter said to me the other day that Maria in The Sound Of Music sounded a lot like Mary Poppins. I said it's because they're both English! I didn't want to say, 'Well, it's because Mary Poppins is really Julie Andrews, who's an actress,' because that would burst that perfect bubble. So I prefer not to deal with it right now."
