Pictures of Naomi Watts' fabulous post-pregnancy body are circulating online after an eagle-eyed paparazzo took pictures of her in the nude.

The unauthorised photographs show the actress standing naked a hotel balcony in Marina del Rey, California, just eight weeks after giving birth.

In the shots, Naomi appears to be oblivious to the presence of a snapper as she lets a dressing gown fall open to reveal her naked post-baby body.

The actress gave birth to baby son Samuel Kai in December.
