The `Your Highness` actress is expecting her first child with fiance Benjamin Millepied but says she`s not really prepared for the impending arrival because of her Jewish upbringing.

She said: "I think it`s a Jewish thing to be kind of superstitious. You don`t do any of the baby stuff before the baby arrives."

However, Natalie says she`s enjoying every moment of her pregnancy and has had no complications.

Speaking during an interview with TV show `Access Hollywood`, Natalie said: "My back is not feeling great right now, sitting for so long. But everything`s really great otherwise."

While she has not bought any baby items, it seems Natalie will be purchasing all things blue after it was reported she is expecting a baby boy.

A source said: "They`ve only told a very small group of family members and friends that they`re expecting a son. They are so excited. Benjamin cannot wait to be a father.

"Natalie had a big smile on her face. She looked amazing."
