Duchess Kate and Prince William's young bridesmaid is all grown up and gorgeous!

Kate Middleton and Prince William's wedding in 2011 offered us a number of breathtaking moments we'll remember for the rest of our lives -- like Kate's stunning Alexander McQueen gown that was custom-made for her big day.

While their nuptials are so memorable that it seems as if it happened yesterday, it's actually been seven years since Wills and Kate said the big "I do." Can't believe it?

Well ... here's a photo of one of Kate and William's bridesmaids -- Margarita Armstrong-Jones. The daughter of the Earl and Countess of Snowden was only 8 years old in 2011. Doesn't she look adorable in her white dress complete with ballet flats and a flower crown?

Fast forward to 2017 ... and she looks nearly unrecognizable! Here she is with her father David Armstrong-Jones and Queen Elizabeth, looking so, so grown up:

Wow!

This year, we're in for quite a treat with a whopping TWO royal weddings to look forward to. Meghan Markle and Prince Harry are set to wed in May, while Princess Eugenie will tie the knot with longtime beau Jack Brooksbank in the fall.
