Meghan Markle and Prince Harry announced their pregnancy in October, and ever since, there's been a new story about Baby Sussex practically every day. Royal fans have watched Meghan's baby kick in her stomach, tried to guess the name, and followed along with the double baby shower drama.
At this point, you may feel like you actually know these people and are waiting for the birth right along with them!
If you want to personally congratulate the Duke and Duchess of Sussex on their first child, you can do that. People explains that you can send your congrats via the Kensington Palace social media accounts. But for a more personal touch, you can also send good old-fashioned snail mail!
The address is:
TRH Duke & Duchess of Sussex
Clarence House
London SW1A 1BA
United Kingdom
Plus, if you do decide to send mail, you might just receive a reply. Meghan and Harry have previously sent thank-you notes to fans who sent their well-wishes, so there's a good chance they'll do the same for this occasion!

As anyone who follows the royal family even a lil' bit already knows, Meghan and Harry are expecting their first baby.
They announced the news back in October, just five months after their wedding.
Meghan is officially gearing up to give birth. She's been taking a break from public engagements, and Baby Sussex is due in a matter of weeks.

Meanwhile, Meghan and Harry are getting ready to settle into their new home at Frogmore Cottage.
Fans of the couple couldn't be more excited to welcome this royal baby to the world.
Over the course of Meghan's pregnancy, fans have been eagerly awaiting details on the baby's name, gender, due date… you name it. People are even wondering whether the baby will wear knee socks, like Kate Middleton's kiddos!
If you're overjoyed for Meghan and Harry and want to personally congratulate them, you can even send a kind note to the address above. That might be the best way to reach the couple, since Meghan reportedly doesn't use Twitter. The royal family deals with A LOT of trolling on social media, and Meghan gets some of the worst of it.
Note that the Sussexes' mailing address is at Clarence House, even though they don't live there. They're moving from Kensington Palace to Frogmore Cottage at Windsor.
But if you accidentally send the letter to the wrong place, that's OK, because the mail will be rerouted to the correct address, People reports!
Last year, many fans sent the Sussexes their well-wishes after the royal wedding in May.

And those who included a return address received a sweet thank-you card from Meghan and Harry in the mail afterward.
The card included a black-and-white wedding portrait of the Sussexes, along with a note on behalf of the couple.
"The Duke and Duchess of Sussex have been overwhelmed by all the incredibly kind cards and letters they have received on the occasion of their Wedding and are so touched that you took the trouble to write as you did,” the note read.
"It really was most thoughtful of you and greatly appreciated by The Royal Highnesses who send you their very best wishes," it continued.
Also, the couple did the same for fans who wished them a happy birthday.
In response to birthday wishes for Meghan, the couple sent a candid photo from the couple's trip to Ireland.
The thank-you notes are quite similar across the board.
For Meghan's birthday:
"The Duchess of Sussex is so touched you took the trouble to write as you did on the occasion of her 37th birthday. It really was most thoughtful of you and Her Royal Highness sends you her heartfelt thanks and best wishes."
Annnd for Harry's birthday:
"The Duke of Sussex is most grateful to you for writing as you did on the occasion of his 34th birthday. It really was so thoughtful of you and His Royal Highness sends you his warmest thanks and best wishes."
That note accompanied a photo of him from 2016 in Guyana.
No promises, but it certainly looks like you'd get a similar thank-you note from the couple if you sent a congratulations for the baby.
Maybe with a photo of Baby Sussex this time?!?!
Don't forget to write your return address on the envelope!
