Unlike Britney Spears or Tom Cruise and Katie Holmes, who kept their latest respective babies under wraps for months, Naomi Watts and her beau Liev Schrieber were not afraid to let their newborn son be photographed. Two week old Alexander Pete Schreiber was seen with a smiling and happy Naomi and Liev out on a trip to the post office on Friday.

As two star parents, they can earn a million or more for exclusive photos of the tot, but they seemed happy and comfortable to give the paparazzi a glimpse ahead of any photo spread they might have planned. You have to respect that, and it’s refreshingly normal.

Commentors on I’m Not Obsessed note that Naomi looks great and that she must have been “all baby.”

On Saturday Naomi and Liev hung out with expectant couple Sacha Baron Cohen and Isla Fischer. Sacha and Liev worked out together and were seen hitting up a sporting goods store ahead of time. Naomi and Isla were said to be back at the house, “cooking for the boys.” [Details from Splash News. The pictures aren’t that great, but here’s one of Sacha and Liev at the store.]

None of the photo agencies we subscribe to have the pictures of little Alexander. You can see the photos at Celebrity Baby Blog and I’m Not Obsessed. Given how open Liev and Naomi were in showing their baby, there are sure to be more photos of the cutie sometime this week.

Here are Liev and Sacha shopping at that sporting goods store on Saturday.
