People Think Prince William Just Revealed His Adorable Nickname for Princess Charlotte

I can't handle how cute this is.

Royals, they're just like us—well, at least when it comes to calling their children adorable nicknames.

We already know that Prince George goes by many monikers, including Archie (which, of course, is also the name of his new cousin Archie Harrison Mountbatten-Windsor). And it seems that his little sister, Princess Charlotte, has also been given some sweet nicknames by her parents, Kate Middleton and Prince William. During the royal couple's trip to Northern Ireland earlier this year, the Duchess of Cambridge revealed that she calls her daughter Lottie.

Now a new video has royal fans thinking they've discovered William's term of endearment for Charlotte.

As part of the reveal of Middleton's Back to Nature garden at the famed Chelsea Flower Show, the Cambridges released some incredibly cute videos of the kids, including a very much on-the-move Prince Louis, frolicking in the space. After asking Prince George how he would rate his mom's creation—she scored a 20 out of 10—the Duke of Cambridge asks his daughter for a push on the rope swing. And if you listen closely, it sounds like he refers to Charlotte as "mignonette."

Check it out for yourself below:

According to Merriam-Webster, "mignonette" is used to describe either an herb or a sauce made with pepper and herbs typically served with oysters. That's an interesting choice of nickname for a child, unless Charlotte is a big fan of oysters (which, honestly, seems entirely possible). But take this into account: According to Babynames.com, the French origin of the word means "favorite" or "darling." My guess is that's what William means when he calls her "mignonette."

It's a fitting nickname for Charlotte considering she is a princess—fans of The Princess Diaries might recall the full name of Anne Hathaway's character, Mia, includes the moniker: Amelia Mignonette Grimaldi Thermopolis Renaldo.

There is some online debate, however, as to whether that's actually what William says. Some think he calls Charlotte over by simply asking, "Have you been on here yet?" in reference to the swing. That might be true, but it's way less adorable.

Either way, the video is worth it just to see Prince William on a rope swing.
