Happy Birthday, Kate Middleton!

The Duchess of Cambridge turned 34 on Saturday, and to celebrate, we rounded up all the times the brunette beauty was ever-so-regal this past year.

The always stylish mom-of-two proved her royal worth in December, when she donned a Knot tiara previously worn by her late mother-in-law, Princess Diana, at the annual Diplomatic Reception at Buckingham Palace. Fabulous!

Two months earlier, Middleton wore a sparkly Lotus Flower tiara -- a piece favored by Queen Elizabeth -- to her first State Dinner in honor of the president of China. Paired with a red-hot Jenny Packham gown, the new "people's princess" looked ever so lovely.

Why hire a professional? The Duchess proved fashion isn't the only thing she has on point -- she also has some amazing photography skills. The birthday girl gifted us with gorgeous photos of her and Prince William's two children -- Prince George, 2, and Princess Charlotte, 8 months -- twice in 2015.

Just two months after giving birth to Charlotte in May, Middleton was already back on her style game, flaunting her post-baby body in an Alexander McQueen ensemble and cream-colored heels while stepping out for the christening of her newborn at the Church of St. Mary Magdalene in Norfolk, England. Because, you know, everyone is ready to rock heels after giving birth…

Proving she's just like us (well, sometimes!), Middleton handled the awkward bangs-growing-out phase like a pro. Instead of covering up her bangs, she let them fly free, not giving a care in the world as photographers snapped pics of them being swept up by the wind.


The Duke and Duchess of Cambridge made all of us envious in June when they met up with Hollywood's royal couple, Angelina Jolie and Brad Pitt, for tea at Kensington Palace.

And we can't forget that time she completely owned the red carpet, showing up to the Spectre premiere in London in a head-turning light blue, flowing frock fit for a princess.
