Julia Roberts doesn't want her kids to know she's an actress. The Pretty Woman star loves that her young children - four-year-old twins Phinnaeus and Hazel and 18-month-old son Henry - still believe films are for real. And Julia insists she has no intention of ruining the illusion.

She says, "I guess I prefer not to deal with it right now. Because the illusion of a movie is a magical and great thing.

Hazel did say that Maria in The Sound of Music sounded a lot like Mary Poppins. "I said they are both English.

I don't want to burst the perfect bubble she has. Mary Poppins is Mary Poppins.  "To say it is really Julie Andrews, who is an actress is ..you want it to stay special as long as you can."
