For some reason when I click the first two links it says the file doesn't exist so I can't see those pictures. The third picture is not actually SMG's body (it's a manipulation... her head is superimposed on someone else's body).
But SMG has an innie belly button (you can see it in the attached picture as well as if you look at the image of SMG on the cover of the September 2001 Entertainment Weekly
link )
