Dare we say Princess Charlotte and Prince George stole the show at Queen Elizabeth II's latest 90th birthday celebration event?

While the monarch stunned in a monochromatic neon green ensemble (complete with matching fascinator, natch) at the annual Trooping the Colour Saturday, Prince William and Kate Middleton's two children nabbed plenty of attention during their first appearance together on the balcony of Buckingham Palace.

As the little ones appeared with their family during the celebration, Middleton carried 1-year-old Charlotte in her arms, while the tiny tyke waved and squinted as she looked up at the sky to see the Royal Air Force's flypast. The princess, who wore a soft pink dress and matching bow in her hair, even flashed smiles as she nibbled on a finger and continued to watch in fascination.

Prince George, too, could hardly keep his eyes off of the sky as the flypast continued. The precocious 3-year-old tot, who sported a white button-down top, smiled and shielded his eyes as he looked up to watch the flypast as well, seemingly captivated by the show. Before it began though, the prince did make sure to wave to the crowd below, and it looked like he gave his family a bit of a scare when he leaned over the balcony a little too far to see what was going down below.

In one photo, George can be seen leaning over the balcony as Prince Philip and Queen Elizabeth look at him concerned and Prince William and Middleton pull him back from the railing. Whew.

Of course, George isn't a novice at these sorts of celebrations. He made his debut on the balcony last June during the Queen's 89th birthday celebration. So, being the pro that he is, the toddler made sure to wave goodbye to the crowd before he left the balcony with his family.

After all, he has to set a good example for his little sis.
