The royal family put on quite the colorful display at this year's Trooping the Colour parade!

Kate Middleton and her daughter, 2-year-old Princess Charlotte, looked pretty in pink on Saturday for the annual birthday event celebrating Queen Elizabeth II, who turned 91 in April.

The Duchess of Cambridge wore a bubblegum pink Alexander McQueen skater dress, which she paired with a matching Jane Taylor hat and teardrop earrings. Her mini-me looked equally fab, sporting a pink polka-dot frock, white socks and berry-colored Mary Janes.

While the mother-daughter duo definitely turned heads in their matching ensembles, Prince George totally stole the show! The 3-year-old donned a cream Peter Pan-collared shirt with burgundy suspender shorts, appearing rather bored as the Royal Air Force show went on.

But it looks like he was just channeling his father, Prince William, who gave the same look at the annual event years ago when he was a toddler.

Too cute!

The Duke of Cambridge currently covers British GQ's July issue, and in his accompanying interview with the magazine, he opened up about his late mother, Princess Diana, who died 20 years ago.

"I would like to have had her advice. I would love her to have met Catherine and to have seen the children grow up," he explained. "It makes me sad that she won't, that they will never know her."
