Catherine, Duchess of Cambridge (or Kate Middleton to you and me), celebrates her 31st birthday today, and what a year she's had!
The wife of Prince William traveled the world in honor of Queen Elizabeth's Diamond Jubilee, cheered on Great Britain as an Ambassador of the Summer Olympic Games, and learned she's expecting the couple's first child!
E! News reports that the Duchess is celebrating privately -- we weren't really expecting a rager given her condition -- and in honor of the day, we've pulled together shots of Kate through the years.
