Princess Charlotte is growing up fast - the royal will turn six on Sunday, rounding off just over a week of celebrations for the Cambridges.
On 23 April, her younger brother Louis turned three and on 29 April, her mother and father celebrated their 10th wedding anniversary.
Charlotte Elizabeth Diana was born on 2 May 2015 in the Lindo Wing of St Mary's Paddington, weighing 8lbs 3oz.
Landmarks around the country were lit up pink for her arrival.
And she made history, as the first female royal to be able to maintain her place in the line of succession. Thanks to a change in the law that was made before her older brother George was born, her younger brother doesn't usurp her spot in the path to the throne.
Over the years, royal fans have watched as the princess has grown into a confident and cheeky young girl.
Who can forget when she playfully poked her tongue out at competitors during the King's Cup regatta, or when she told photographers "you're not coming" after the christening of little brother Louis?
And we all wonder what she was thinking when she put her hand in front of her face at cousin Eugenie's wedding to Jack Brooksbank in 2018.
Here are some of the royal's best show stealing moments.
