Kate Middleton and Prince William won't be spending Valentine's Day together

Valentine's Day is all about spending time with your significant other, right? Well, not for the Duke and Duchess of Cambridge. Word on the street is that Prince William and Kate Middleton will be spending the holiday apart this year.

The royals, who have already stepped up their responsibilities for 2017 (they chose to forgo their annual Mustique vacation with the Middleton clan in favor of starting royal duties earlier in the year), are in the process of making the move back to London full time. Judging from the hedge being built to block out neighbors and talk about George's school in the fall, plans are in motion to make Kensington Palace their permanent home this summer.

So as it turns out, stepping up royal duties might also mean not getting to spend the romantic day with each other.

Kensington Palace confirmed earlier this week that Duchess Kate will be visiting a Royal Air Force base in Cambridgeshire on her own on the 14th, marking her third trip to the base. She recently took over the position as Patron of the RAF in 2015, after the Duke of Edinburgh served as Air Commodore-in-Chief for 63 years.

If we know anything about the Duchess, though, she's happy to fulfill the commitment, even if it does fall on Valentine's Day. Plus, the two always seem to make it work no matter how far away they are from each other.

On February 14 in 2012 -- during Kate's first full day of public engagements without William -- Kate revealed that her new husband had managed to send her flowers and card. Aw!

And while we're taking this particular part of the story with a grain of salt, the rumor mill is spinning with claims that William's grandmother, Queen Elizabeth II, is responsible for the pair's separate plans.

Well, what grandma (or you know, the Queen) says, goes.
