Princess Charlotte recently made headlines after she stuck her tongue out while at the charity regatta.

At that time, Princess Charlotte was accompanied by her mom, Kate Middleton. Shortly after her hilarious video was released, several publications claimed that the young royal inherited her habit from Prince Harry.

But the truth is, the public doesn’t have to look very far to know that Princess Charlotte actually inherited her habit from an immediate family member.

When Prince William was still very young, he was also photographed sticking his tongue out while being carried by Princess Diana. In another snap, Prince William is wearing his groomsman attire when he stuck his tongue out at the young girl beside him.

Several years later, the Duke of Cambridge was also photographed sticking his tongue out while at a royal family affair.

But on the online forum site Quora, royal fan Eileen Wood said that tongue-sticking is not a trait that is exclusive to the Cambridges. After all, several other members of the royal family have also been photographed while they tongue are out.

For instance, Queen Elizabeth and Prince Philip have also been seen doing a similar gesture while they were out in public. And when Prince Charles and Princess Anne were still young, they also stuck their tongues out while being photographed.

Prince Harry has also been sticking his tongue out ever since he was a kid. And he is also known to make funny faces in front of the cameras.

Meanwhile, royal fans recently weighed in on whether or not Middleton’s reaction to what Princess Charlotte did was appropriate. After the Duchess of Cambridge saw Princess Charlotte sticking her tongue out at her grandfather, Middleton laughed but she immediately stopped her daughter.

Royal fans said that Prince William’s only daughter is only 4 years old and it’s very normal to not know how kids will react while they are in public.
