Princess Charlotte and Prince George Steal the Show at Queen Elizabeth II's Parade

Royal family continues to celebrate the monarch's 90th birthday

Princess Charlotte has reached a milestone!

The adorable 13-month-old daughter of Prince William and Kate Middleton, along with brother Prince George, absolutely stole the show during Queen Elizabeth II's birthday parade when they appeared on the Buckingham Palace balcony. The young tots joined their parents, Prince Harry, the Queen and her husband, Prince Philip, as they greeted onlookers and waved to those who wanted to wish the Queen well. It was Charlotte's balcony debut, and let's just say she owned it in the cutest way possible.

Wearing a pink dress with a matching pink bow and shoes, Charlotte gave the people her biggest smile and a wave. The Duchess of Cambridge couldn't help but smile and laugh at her daughter, who obviously has figured out the ways of the royals! A little while later, however, the planes that flew overhead seemed to be too loud for Charlotte, so she covered her ears.

George, 2, who was carried out onto the balcony last year, proved how much he has grown up by walking out onto the perch without any help. He also proved he mastered the royal wave by giving the customary Windsor greeting. His outfit, a white collared shirt with a Peter Pan collar edged with blue trim and blue shorts, looked similar to the one Prince William once wore to his younger brother's christening when they were kids.

How time flies!

Not to be overlooked, the Queen, who is celebrating her 90th birthday, made sure she was noticed by wearing a lime green ensemble with a matching green hat. The bright outfit was accented with a neon pink flower. Wills and the Duke of Edinburgh, however, wore traditional regalia.

The parade is just one part of the weekend celebrations honoring the Queen, who turned 90 in April. Britain's longest reigning and oldest sovereign, the Queen received a special thanksgiving ceremony at St Paul's Cathedral Friday, where politicians, family and more lauded the Queen's work throughout the years. It also happened to be Prince Philip's 95th birthday.

When the royals celebrate, they celebrate big.
