The royally gorgeous Duchess of Cambridge has officially welcomed her third child with Prince William, a baby boy, and considering she's one of the most beloved women in the world (both by the adoring public and her precious little family), we'd say Middleton has plenty to celebrate.

The last year was certainly a momentous one for the duchess: Middleton announced her pregnancy, sent her son Prince George off to school for the first time, and came one step closer to having a new sister-in-law, as Prince Harry announced his engagement to Meghan Markle.
