Photos of Prince George playing with toy gun spark heated debate

We're used to seeing Kate Middleton in polished ensembles for royal events, but over the weekend, the Duchess of Cambridge proved she can also nail casual weekend style.

George, 4, and Charlotte, 3, were seen running, jumping and laughing as they and their mom, Princess Kate, supported Prince William at the Maserati Royal Charity Polo Trophy at Beaufort Polo Club.

George and his friends were spotted playing with some toy guns.

It was a family affair for the Royal family on Sunday. But all eyes were on the youngest royals who stole the show at the parade - particularly the delightful banter between Prince George and his cousin Savannah Phillips.

After the pictures emerged, several people took to Twitter to voice their outrage and suggest that the royal family should have been more mindful about the toys they give Prince George and Princess Charlotte. As crowds sang God Save The Queen, Savannah put her hand over the mouth of Prince George, causing many people to dub it the funniest moment of the day.

By then little Charlotte, who appeared to shout after her mum as she sprinted to the marquee, was by her side.

Charlotte attempted headstands and pranced around the grounds, much to the amusement of her mother, who could be seen having a hearty laugh while her daughter was upside down.

Sitting on a grass slope together, Savannah, 7, was pictured with her arm around Charlotte. (It appears that George, who asked for a toy police vehicle for Christmas, is still very interested in law enforcement.) While it's not unusual whatsoever for kids to play pretend, some people are taking issue with Middleton for allowing him to play with a toy that looks so similar to a real-life gun.

Over the course of the day, the little royals could be seen playing with a huge slinky, a miniature golf set, arts and crafts and the controversial toy gun.
