Duchess Kate turns 30 on Monday, and she's never looked better!

Prince William's now-wife first walked into his life in 2002, when the curvy brunette strutted down the runway for a St. Andrew's charity fashion show. 

Throughout the royal couple's pre-wedding romance, Kate's figure fluctuated, and at times she was super svelte and others slightly curvier.

Prior to her fairytale wedding in April, the Duchess looked notably slimmer, wowing crowds with her lithe frame. She looked trim and impeccable on April 29 when she walked down the aisle in a custom-designed Alexander McQueen gown by Sarah Burton. 

Although still thin, Kate sparked pregnancy rumors in November when she refused peanut paste at Copenhagen's UNICEF distribution center. Although she has no allergy to peanuts, pregnant women are often encouraged to avoid them to prevent the development of allergies in newborns. 

Since the incident, however, she's shown she's not expecting in a series of fitted dresses showcasing her teeny waist!
