There is a law in California restricting the rights of photographers to take pictures of celebrities children. There was a lot of lobbying done to get this done. It was meant to protect the children of the celebs (and rightly so, since the children did not choose this line of work). So I hope they sue the paper for this, and if they don't, that proves that she arranged this pap shot.
You cannot see her smug/smiling face because of the mask, but you can see it in the eyes. You can tell when someone is smiling by looking at their eyes, and if it was a candid photo then why would she be smiling. The child on the hip is weird for someone that is heavily pregnant, I would think its not advised to light heavy objects at that stage of the pregnancy. I agree with other comments that she looks skinnier in those pictures than she did on the Oprah interview. She looked more bloated in the face in the interview, but that could've just been temporary and in her last pregnancy I think she wasn't really heavy anywhere else.
