We look at pictures of Kate Middleton over the years - from her childhood to becoming a princess...

Well this is a first for Kate!

During a visit to Wimbledon in July 2016, Serena Williams posted an adorable video of herself and Kate on Snapchat, exclaiming 'I'm with royalty!' Whilst the Duchess looks a little confused at the concept at first, she soon gets the hang of it, sharing a big smile for the camera.

Both William and Kate are known to be avid tennis fans, but Kate also revealed to former British number one Greg Rusedski that George is already following in their footsteps, and has taken up the sport at the age of just 2.

'She talked about George, her little boy, playing tennis,' Greg said. 'He's got a racket and he enjoys playing tennis, and obviously she plays with William, so they obviously enjoy the sport very much.'

Kate Middleton: 1985

Life has changed a lot for Kate Middleton over the last few years. The once normal girl has been transformed into a princess (well, Duchess) and become the nation's sweetheart.

Kate was just a normal university student when she met Prince William and her life turned upside down. She has weathered a very public break-up, a royal wedding and and gave us an adorable Prince and Princess. One thing's for sure, Kate's emerged as an elegant young woman the public love!

And to think it all started with this adventurous 3-year-old little girl!
