The seemingly pregnant belly sported by the wife of North Korean leader Kim Jong Un in mid-December appeared to be gone by New Year's Day. That's sent South Korean media into a frenzy of speculation that there's a new baby in the ruling Kim dynasty. (AP Photo/KRT via AP Video, File) NORTH KOREA OUT, TV OUT
