I've been a member of Score's Kerry Marie site lately, and while she has put on a few pounds, I would say it's not necessarily a sign of pregnancy. She's always had a pudgy stomach, and that just happens to be where some extra pounds have went. In addition to a couple of other nice places.
Don't get me wrong, I would be tickled to death to see her pregnant - I don't suspect that she is from what I've seen, but only time will tell.
