Meh, that is - sadly - probably merely an awesome rumor. Though it is also true that if the rumor is untrue, she was far less cautious than I might have been about her own health and the health of the fetus (all the stuff about giving a speech at a conference in Texas and then taking an 11-hour flight back to Alaska after her waters broke would be true, if it really was her pregnancy.) Plus she went back to work like three days after the baby was born. But then this was her fifth pregnancy, so maybe she was just really, really relaxed about it?
