We've spotted the Desperate Housewife and soon-to-be mother-of-two sporting this white bucket hat before in order to duck away from our cameras' unblinking eyes, but for the life of us, we can't figure out why - she may be bigger than she's ever been due to her looming date with a delivery room, but that's no reason to be ashamed!
