By now, you've probably heard the reports of an intense and ongoing feud between Meghan Markle and Kate Middleton.
While it's true that the British tabloid press would probably have these two at each other's throats even if they were the best of friends, there's legitimate reason to believe Meg and Kate genuinely dislike one another.
For starters, Kensington Palace issued a statement in the feud, which is a virtually unprecedented move by the Royals' press secretaries.
On top of that, Meg and Kate have both been suspiciously silent on the matter.
It's a curious situation, and it's not hard to see why it's captured the imagination of royal watchers the world over.
Much ink has been spilled on the question of what caused the split, and it seems like -- as is usually the case with fractured relationships -- there were a number of contributing factors.
Last week, we talked about the peace summit that Prince Charles hosted at Anmer Hall last Christmas in hopes of soothing what were then simmering tensions between the two duchesses.
Yesterday, we discussed reports that relations broke down for good when Meghan and Kate fought over a dress (specifically, the fit of Princess Charlotte's dress) just prior to Meg's wedding.
Now, we're receiving word that there's another barrier preventing Meghan and Kate from forming a friendship -- and it's been present since the first day they met.
There have long been reports that Meghan is "too American" for the Royals' liking, and it seems Kate finds her Yankee demeanor particularly troublesome.
According to People magazine (long the most reliable source on this sort of royal gossip), Kate is often repulsed by Meghan's brusque way of addressing palace staff.
A source close to the situation tells People that royal aides “might not be used to the ‘say-it-as-you-see-it’ American mentality."
A different insider claims that Meghan learned early on that she needs to be outspoken and persistent if she's going to accomplish the goals she has in mind as Duchess of Sussex.
“The palace is a magical place, and it is also a place where all you hear is ‘no, no, no,’ ” says the source.
Sounds to us less a matter of national identity and more a simple fact of two very different personalities occupying the same space.
