Princess Charlotte looked especially adorable during the wedding of Princess Eugenie.

Princess Eugenie recently shared a never-before-seen photo taken during her royal wedding featuring the bridesmaids and pageboys on Instagram. In the snap, Prince William and Kate Middleton's only daughter, Princess Charlotte, can be seen grinning at the camera.

According to Katie Harris, a journalist for Express, the 3-year-old royal stole the show. Princess Charlotte's smile is very adorable. She seemed so please with whatever they were talking about that she even closed her eyes while laughing. Another bridesmaid, meanwhile, hugged the bride. The photo was filled with love and joy.

"Jack and I would like to thank everyone who was involved in making our day so special and for all the wonderful wishes as we start married life laughing together," she wrote in the caption.

This isn't the first time Princess Charlotte has stolen the show. When the Duke of Cambridge arrived with her and Prince George to visit Middleton after delivering Prince Louis last April, she won over the crowd with her royal wave and sweet smile. On the other hand, her older brother was too shy to greet the citizens.

Although Princess Charlotte was in high spirits in the snaps, there were also shots when the little princess appeared to be not in the mood. Princess Charlotte and Prince George had respective roles to fill during the wedding and it's understandable that they also got tired and cranky.

According to an insider, Princess Charlotte is "very bubbly," noting that "she's definitely the biggest character of the three children at the moment."

Princess Charlotte is also fond of her mom. In fact, she often imitates what the Duchess of Cambridge does when they welcome guests. "She'll come up to guests and ask them if they want tea or coffee or offer them sweets — so adorable!" the source said.

In related news, Princess Charlotte is already showing signs that she has inherited some traits from her late grandmother, Princess Diana. They don't only look the same, but they also share the same passion for horseback riding and dancing.

Middleton told equestrian Natasha Baker that Princess Charlotte is enjoying riding and that she has "this passion for horses." The Duchess of Cambridge doesn't share the same fondness for horses, but promised that she'll do her best to encourage her daughter to champion it. Meanwhile, it was Prince William who announced that dancing is Princess Charlotte's new hobby.
