The pictures of the young royals mirrored the same photographs shortly after Charlotte's birth. In 2015 when the first portraits of baby Charlotte were released, one of the photographs showed proud big brother George bestowing a gentle kiss on his baby sister. Meanwhile, just hours after Prince Louis' arrival, Charlotte was every inch the proud big sister as she arrived at the Lindo Wing to meet her newborn baby brother for the first time. Accompanied by her father Prince William and Prince George, the young royal appeared to be in great spirits as she waved at the crowd outside St Mary's Hospital in Paddington.

Prince George and Princess Charlotte charmed crowds as they visited their mum in hospital shortly after Prince Louis' arrival. Prince William briefly left the hospital to pick the pair of them up after George finished school, and the pair were photographed holding hands with their dad while making their way to the hospital, with little Charlotte turning around to give the crowds an adorable extra wave.

Princess Charlotte was recently pictured having the time of her life at a polo match. She and her brother were playing with a pair of handcuffs and walkie talkies for kids. Throughout the day, the duo also played with a slinky and toy guns, among other toys Kate Middleton brought for them.

During Prince William and Kate's tour of Canada in 2016, both George and Charlotte stole the show. At a garden party, held at Victoria's Government House, Charlotte was seen looking intrigued, while her big brother looked like he was having a ball whilst trying to get her attention with his Finding Nemo bubble gun.

Kate has previously joked that Charlotte is "in charge" of her big brother, but that the youngsters are "very good friends". During a children's tea party at the Natural History Museum, the Duchess also revealed that Charlotte was "extremely chatty" and "always wants to have a play date" with her sibling.

Princess Charlotte has shown an interest in football along with her older brother George. With a dad who loves Aston Villa, it's no surprise that the pair are also Villa fans. Kate has previously revealed that her youngsters "love putting on Villa kits" and cheering on their dad's favourite football team.
