My son has no idea what I do for a living, says Sandra Bullock

London: Sandra Bullock has revealed that her son has no idea what she does for a living.

She may be an Oscar-winning actress but to her young son Louis she`s just "mom" and she plans to keep it that way.

The `Gravity` star has gone to great lengths to shield her three-year-old from discovering her celebrity status as she thinks it`s healthier.

The 49-year-old added that she`s hoping to keep him away from what she does for as long as possible.
