The Duchess of Cambridge has officially popped. Kate Middleton and Prince William were spotted during a charity visit for the Child Bereavement Offices of the UK. And no matter how she tried to hide the budding bump under her winter white coat, either with a bouquet of flowers or a teddy bear, there was just no disguising the little heir to the throne. The Duchess was absolutely glowing at the event. Underneath her wool coat, she wore a simple little black dress, tights, and pumps.
