We just can't get enough of watching Princess Charlotte grow, and every time we see her she's even more like Kate.

The royal baby delighted crowds outside Buckingham Palace today, making her first appearance on the famous balcony as part of the Queen’s 90th birthday celebrations.

Princess Charlotte appeared on the balcony in Kate’s arms, while Prince William talked big brother Prince George through the festivities.

Of course, this is George’s second official appearance on the Palace balcony, and it seems he’s already well-seasoned in royal protocol – not one little bit of boldness in him!
