Naomi Watts suffered a bit of online embarrassment this weekend when she was spotted naked on a balcony in California.

Now she’s pregnant? WTF?

Watts is on set in California wearing a fake 9 month pregnancy belly for her new film Mother And Child, a drama written and directed by Robert Garcia, the director of the similarly dark 21 Grams, also starring Watts. In the film, it’s rumored that the belly worn by Watts is the baby made with a character played by Samuel L Jackson.

The story of the film follows three women, a 50 year old woman, the daughter she gave up for adoption and a woman looking to adopt a child of her own. If I were to guess, I’d say that Naomi Watts is woman number two and Annette Benning, also attached to the project is woman number one.

If big names fall into lead roles, then the safety guess for woman number two would be Kerry Washington, last seen with Jackson in Lakeview Terrace.

The naked pictures of Watts seem to stem from a scene in this movie that includes full outdoor nudity for Naomi, though the paparazzi couldn’t be held back.

Mother and Child is slated for release in 2010.
