Washington, May 17: Penelope Cruz has revealed that she kept her post delivery life a secret because she wants her son to grow anonymous.

The star revealed she was expecting her first child with husband Javier Bardem only a few short weeks before arriving on the set of `Pirates of the Caribbean: On Stranger Tides'.

"I was pregnant and a pirate. A beautiful experience," People mag quoted Cruz as saying in the June issue of Vogue.

However, in an effort to keep her personal life private, Cruz has kept the pregnancy, son Leonardo`s January birth, and life as a new mom out of the spotlight.

"I want my son - and my kids if I have more - to grow up in a way that is as anonymous as possible," said the Spanish actress.

"The fact that his father and I have chosen to do the work that we do, doesn't give anybody the right to invade our privacy," she added. (ANI)
